     FIELD OF THE INVENTION 
     The present invention relates to fluid flow systems, and more particularly to a push-fit joint assembly, system and method that facilitates the repair and re-use of piping and tubing system parts without coining or threaded end caps. 
     BACKGROUND OF THE PRESENT INVENTION 
     Piping systems exist to facilitate the flow of fluids (e.g., liquid, gas (such as air) or plasma). For example, homes, schools, medical facilities, commercial buildings and other occupied structures generally require integrated piping systems so that water and/or other fluids can be circulated for a variety of uses. Liquids and/or gases such as cold and hot water, breathable air, glycol, compressed air, inert gases, cleaning chemicals, waste water, plant cooling water and paint and coatings are just some examples of the types of fluids and gases that can he deployed through piping systems. Tubing and piping types can include, for example, copper, stainless steel, CPVC; (chlorinated polyvinyl chloride) and PEX (cross-linked polyethylene). For purposes of the present disclosure, the term “pipe” or “piping” will be understood to encompass one or more pipes, tubes, piping elements and/or tubing elements. 
     Piping connections are necessary to join various pieces of pipe and must be versatile in order to adapt to changes of pipe direction required in particular piping system implementations. For example, fittings and valves may be employed at the ends of open pieces of pipe that enable two pieces of pipe to fit together in a particular configuration. Among fitting types there are elbows, “tees”, couplings adapted for various purposes such as pipe size changes, ends, ball valves, stop valves, and partial angle connectors, for example. 
     In the past, pipe elements have been traditionally connected by welding and/or soldering them together using a torch. Soldering pipe fittings can he time-consuming, unsafe, and labor intensive. Soldering also requires employing numerous materials, such as copper pipes and fittings, emery cloths or pipe-cleaning brushes, flux, silver solder, a soldering torch and striker, a tubing cutter and safety glasses, for example. The process for soldering pipes can proceed by first preparing the pipe to be soldered, as the copper surface must be clean in order to form a good joint. The end of the pipe can be cleaned on the outside with emery cloth or a specially made wire brush. The inside of the fitting must be cleaned as well. Next, flux (a type of paste) can be applied to remove oxides and draw molten solder into the joint where the surfaces will be joined. The brush can be used to coat the inside of the fitting and the outside of the pipe with the flux. Next, the two pipes are pushed together firmly into place so that they “bottom out”—i.e., meet flush inside the fitting. The tip of the solder can be bent to the size of the pipe in order to avoid over-soldering. With the pipes and fitting in place, the torch is then ignited with the striker or by an auto-strike mechanism to initiate soldering. After heating for a few moments, if the copper surface is hot enough such that it melts when touched by the end of the solder, the solder can then be applied to the joint seam so that it runs around the joint and bonds the pipe and fitting together. 
     In recent years, push-fit technology has been employed with piping systems to reduce the dangers and time involved in soldering joints. Push-fit methods require minimal knowledge of pipe fittings and involve far fewer materials than soldering. For example, one may only need the pipes, quick-connect fittings, a chamfer/de-burring tool and tubing cutter in order to connect pipes using push-fit technology. 
     The steps involved in connecting piping systems using push-fit technology can be outlined as follows. First, the pipe is cut to the appropriate length and the end of the pipe is cleaned with the de-burring tool. Then the pipe and fitting are pushed together for connection. The fitting is provided with a fastening ring (also called a collet, grip ring or grab ring) having teeth that grip the pipe as it is inserted. The fastening ring device is employed to provide opposing energy, preventing the device from disconnection while creating a positive seal. Accordingly, no wrenches, clamping, gluing or soldering is involved. Push-fit and/or quick-connect technology for piping systems can be obtained, for example, through Quick Fitting, Inc. of East Providence, R.I., USA, suppliers of the CoPro® line of push fittings and related products. Also, such technology is described, for example, in U.S. Pat. No. 7,862,089, the disclosure of which is incorporated herein by reference in its entirety. 
     In past pipe coupling technology, the fastening ring is inserted into the fitting body along with a plastic grip ring support that typically fails under extensive tensile testing. Further, the coupling must then be either coin rolled, glued or receive a threaded cap member to retain the fastening ring inside the fitting body. In addition to the added steps for the manufacture and assembly of the coupling, the strength of the plumbing joint is determined by the retaining cap member. The additional steps and components add significant labor and manufacturing costs to the final product cost and reduce the overall production capability due to the extensive time required for proper assembly. 
     In addition to the above, when using a threaded retaining cap method, the process of cutting threads into the fitting body and the retaining cap elevates the cost of machining the fitting components. Further, the threaded end cap method requires mechanical assembly as well as the added cost and application of a thread sealant to the threads. In prior efforts that employ a coined retaining cap method, the process of coining the fitting body as the retaining cap significantly increases the cost of final assembly of the fitting. Additionally, the coining process permanently encapsulates the fastening ring inside the fitting, whereby the fastening ring cannot be removed without complete destruction of the ring and fitting. 
     Along with additional assembly steps and increased manufacturing costs, past pipe fittings and connection methods do not allow repair for various reasons. In some cases, this is because they are factory sealed, for example. In other cases, it is because the separation of the fitting from the pipe can damage or induce wear on the parts. For example, some push-to-connect fittings provide permanently fixed demounting rings for removing the fittings. The demounting rings can be depressed axially to lift the fastening ring teeth off of the surface of the inserted pipe, such that the pipe can then be withdrawn. This arrangement, however, can subject the fittings to tampering and shorter life. In addition, while fastening ring devices work effectively as an opposing retaining member, their functionality makes them nearly impossible to dismount, remove or detach for re-use. The fastening rings are thus permanently affixed unless they are cut and removed, which then destroys the fastening ring. 
     Whether connected by traditional soldering methods or with push-fit methods, past efforts have been specifically provided for the connection of like materials and lack the ability to connect two unlike materials, such as copper with CPVC, HEX or stainless steel, or any other combination of unlike materials. Past methods further invariably require the replacement of fittings and valves, and do not allow re-use of the fittings or valves in instances where only a small internal component needs to be repaired or replaced. 
     SUMMARY OF THE PRESENT INVENTION 
     The present invention provides, in part, a push fitting assembly package that facilitates the re-use of push fittings without damage to the fitting elements or the pipe. The present invention connects piping using no tools, clamps, solder or glues, while creating a leak-free seal at the connected joining area. Further, unlike prior methods, the present invention can join both like and unlike piping elements in any combination, and without coining or threading the elements into place. 
     The quick connection pipe joint assembly package provided as part of the present invention employs a one-piece retaining ring and pusher that, when removed, exposes the clamping, sealing and fastening mechanisms of the fitting. The retaining ring and pusher member (“release pusher” for purposes of this disclosure) moves axially and can push the fastening ring of the present invention in order to facilitate the release of a cylindrical object such as a piping element held within the fitting. 
     For purposes of the present disclosure, a fitting (also referred to as a body member) can encompass a valve member and other piping elements including, but not limited to: a coupling joint, an elbow joint, a tee joint, a stop end, a ball valve member, tubing and other objects having cylindrical openings. In one embodiment of the present invention, one or more sealing member gasket inserts (e.g., O-ring members) fits within a first radial housing element defined in the interior wall of the fitting. In addition, at each pipe receiving end of the fitting, a second radial housing element is machined into the interior wall to retain the edges of the fastening ring. The interior housing elements provide integrated support for the sealing members and fastening ring when opposing force is applied to piping elements that have been inserted into the fitting. In one embodiment, a flexible metal support snap ring gland member is employed to provide additional support for the fastening ring. 
     One aspect of the present invention provides a novel push fitting joint packaging arrangement comprising a split fastening ring and a split o-ring support member. The split fastening ring can include a first and a second circumferential end point that do not connect, wherein the first and second end points include facing edges, and wherein the facing edges extend substantially radially outwardly along respective radial axes of the ring. The split o-ring support member can include a first and a second circumferential end point that do not connect, wherein the first and second end points include facing edges, and wherein the facing edges are not aligned with respective radial axes of the support member. The present invention can further comprise a split spacer member between the split o-ring support member and the split fastening ring. The split spacer member can be a separate member from the fastening ring, or can be integrated with the split fastening ring so as to form a crown-like member, 
     In one aspect of the present invention, once the fastening ring is inserted into the fitting, the fastening ring does not require any additional method or device to retain it under opposing force. The integrated radial housing element provides for a more stable fastening ring connection with the ability to withstand significantly higher tensile pulling forces than the prior art. As a result, the stability of the quick fitting fastening connection is not determined or co-dependent on a plastic retainer, threaded end cap or machined coined retainer. 
     The release pusher provided as part of the present invention is primarily employed to facilitate the release of tubing, piping and other cylindrical objects inserted into a fitting. The release pusher is manually pushed into the fitting body and tapered edges of the release pusher generally or nearly abut the installed fastening ring. When it is desired to release an inserted pipe, for example, from the fitting, the release pusher can be forced in the direction of the fastening ring such that its angular surfaces depress the fastening ring teeth off of the surface of the inserted pipe, thereby allowing the pipe to be removed,

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     In the push-fit piping joint assembly  10  as shown in  FIGS. 1 and 2 , elements of the joint assembly as shown include: a fitting(i.e., fitting body member)  12  having an inner wall  13  and outer wall  15 , a fastening ring  18 , two substantially identical sealing members  14 ,  16  (which can be optionally lubricated) and a release pusher  20 . The fastening ring and sealing members together provide one embodiment of a packing arrangement for the present invention, and each has an internal diameter that allows for smooth and snug engagement of a piping or tubing element external surface  24 . The fitting  12  is substantially hollow with a pipe receiving opening  100  therein. In one embodiment, the interior diameters of the fastening ring  18  (as measured to the teeth  19  and not the ring cylindrical base) and sealing members  14 ,  16  are substantially the same, and the interior diameters of the fitting  12  and the release pusher  20  are substantially the same. Further, the interior diameters of the fastening ring  18  and sealing members  14 ,  16  are slightly less than that of the fitting  12  and release pusher  20  so as to facilitate proper operation of the present invention. The release pusher  20  is substantially cylindrical and includes an external tip  21  at the fastening ring engaging end thereof. 
     In one embodiment, the fitting  12  can be forged CW617N brass, with full porting and full flow fitting, for example. The lubricant for the sealing members  14 ,  16  can be a food grade lubricant, for example. It will be appreciated that the sealing members can comprise a flat ring or washer-type seal member in addition or as an alternative to a circular member of substantially circular cross-section. The fastening ring  18  can comprise a spring steel formulation, for example, that enables the fastening ring to be malformed during installation, while springing back into its originally manufactured position once installed. The fastening ring is capable of grabbing an inserted pipe&#39;s surface via two or more teeth  19  to ensure connections cannot be pulled apart. The fastening ring teeth are angled downward from the substantially cylindrical perimeter of the ring, toward the fitting and away front the cap, such that when the pipe is inserted, the teeth exert a pressure against the pipe to discourage the pipe from slipping or moving back out of the fitting. No wrenches, solder, welding, glue and/or twisting and turning the elements are required to form a connection. Specifically, the combination of the fastening ring, an O-ring support member and a fastening ring crown provide a push-fit piping assembly when inserted into any cylindrical pipe. 
     As shown in  FIGS. 3 ,  4  and  8 , for example, the release pusher  20  includes a radially outer ledge  26 , the external tip  21  and outer wall segments  25 ,  27 . The release pusher can comprise an injection-molded plastic material or a metal material such as brass, for example. When pressure is applied on the back side  30  of the release pusher  20 , the external tip  21  can engage the inside surface  32  of the fastening ring teeth  19  as will be described in more detail below, and the ledge back wall  29  can removeably engage a retaining lip  34  extending radially inwardly of the fitting inner wall  13  at the axially outermost position of the fitting, as shown in  FIG. 3 . 
     In one embodiment of the release pusher of the present invention, the outer wall segments  25 ,  27  comprise a single linear segment from the radially outer ledge to the external tip. In another embodiment of the present invention, as shown in  FIG. 8 , the first outer wall segment  25  extends linearly at a first angle C from the radially outer ledge  26  to an outer wall intermediate point  36 , and the second outer wall segment  27  extends linearly from the outer wall intermediate point  36  to the external tip  21  at a second angle D. 
     During removal, a tool such as a specially adapted wrench, for example, can be applied to the outer top surface of the release pusher so as to exert a pushing and lifting force that causes the release pusher outer ledge to disengage the retaining lip  34 . Once the release pusher is removed, the internal packing arrangement components are exposed for removal and/or replacement. 
     As shown in  FIGS. 2 through 7 , the fitting  12  is formed with first  40  and second  42  radial housing elements. The first radial housing element  40  houses sealing members  14 ,  16 , and the second radial housing element  42  houses the fastening ring  18 . The sealing members can be housed so as to substantially abut one another within the first radial housing element  40 . Further, the sealing members  14 ,  16  are shown axially inward of the fastening ring  18 , when in position within the fitting  12 . In the embodiment shown in  FIGS. 12 through 14 , the second radial housing element  42  also houses a support snap ring gland member  90 , described in more detail below. 
     The first radial housing element  40  is formed by a first housing back wall segment  44 , the fitting inner wall  13  and a housing separator segment  46 . The second radial housing element  42  is formed by the housing separator segment  46 , the fitting inner wall  13  and a second housing front wall segment  48 . The inner wall  13  is not labeled within the recesses of the housing elements  40 ,  42 . As shown in  FIG. 7 , the second housing front wall segment  48  has a top angled guiding surface  50 , which permits sliding engagement with the fastening ring circumferential base  52  (shown in  FIG. 10 ) when the fastening ring  18  is either being inserted or removed. The top angled guiding surface  50  of the second housing front wall segment  48  extends from the fitting inner wall  13  at an axially outer position  53  thereof to a front wall segment tip  54  at an axially inner position  55  of the fitting inner wall  13 . 
     As shown in  FIG. 6 , the housing separator segment  46  has a plateau surface  58  and a front wall  60  with a front tip  62 . The housing separator segment also includes a top angled backing surface  64  that extends from the front wall tip  62  to the plateau surface  58 . In one embodiment of the present invention, the distance E from the fitting inner wall  13  to the separator segment front tip  62  is approximately the same as the distance from the fitting inner wall  13  to the second housing front wall segment tip  54 . In another embodiment of the present invention, as shown in  FIG. 5 , the distance E from the fitting inner wall  13  to the separator segment front tip  62  is less than the distance from the fitting inner wall  13  to the second housing front wall segment tip  54 . This distance E can be changed as necessary to facilitate engagement and movement of the fastening ring  18  within the second radial housing element, as desired. As shown in  FIG. 7 , the top angled guiding surface  50  of the second housing front wall segment  48  can extend at an angle A measured from the fitting inner wall. Further, as shown in  FIG. 6 , the top angled backing surface  64  can extend at an angle B measured from the fitting inner wall. In one embodiment of the present invention, angles A and B are substantially the same. In one embodiment of the present invention, angle B can range from approximately 9 degrees to approximately 52 degrees, and angle A can range from approximately 6.5 degrees to approximately 50 degrees. Further, in one embodiment of the present invention, angle B is greater than angle D of the release pusher  20  (see  FIG. 8 ) so as to facilitate proper operation of the present invention as described below. 
     As shown in  FIGS. 1 and 9  through  11 , the fastening ring  18  can be a split ring member having a circumferential base  52  and two circumferential end points  66  that do not connect. The fastening ring can further include fixture points  68  for handling and compressing the fastening ring. In one embodiment of the present invention, the fixture points  68  are provided at the split end so that a tool designed to hold the fastening ring at the fixture points can more easily handle and compress the fastening ring in order to assist with assembly or disassembly. For example, as shown in  FIG. 10 , a first fixture point  68  can be included on the left edge of a first tooth that extends from the circumferential base  52 , such that the right edge of the first tooth is flush with the first circumferential end point  66 . A second fixture point  68  can be included on the right edge of a second tooth that extends from the circumferential base  52 , such that the left edge of the second tooth is flush with the second circumferential end point  66 . Once compressed, the fastening ring is easily insertable into the second radial housing element  42  of the fitting  12  by releasing the hold on the fixture points  68 , thereby allowing the fastening ring to expand such that the circumferential base engages the walls of the second radial housing element. The fastening cart be removed from the second radial housing element in similar manner. No wrenches, solder, welding, glue and/or twisting and turning the elements are required to form or disengage a connection. 
     The fastening ring  18  includes a substantially cylindrical base  52  that has a plurality of bifurcated or square edged teeth  19  extending inwardly from and along the base of the ring  52 . As shown in  FIG. 9 , the teeth  19  of the fastening ring  18  can extend at an angle F from the horizontal axis G, wherein F ranges from approximately 39 degrees to approximately 68 degrees. In one embodiment of the present invention, angle F is approximately 56 degrees. These angles are measured when the teeth are at rest position and are not stressed by the insertion of a pipe. In one embodiment, each tooth has a substantially squared off edge, comprising a left edge, a right edge and a bottom edge. The top edge of each tooth is integrally connected to the circumferential base  52  of the fastening ring  18 . The number of teeth can readily vary in number and size. 
     In operation, the fitting  12  of the present invention is provided and one or more sealing members  14 ,  16  are inserted into the first radial housing element  40 , as shown in  FIG. 3 . Next, the fastening ring  18  is inserted into the second radial housing element  42 , and release pusher  20  is snapped into engagement with the retaining lip  34  of the fitting  12 . When a pipe  70  is inserted, it travels through the release pusher  20  into the pipe receiving cavity  100  of the fitting  12 , engaging the fastening ring  18  and the one or more sealing members  14 ,  16 . The sealing members provide a strong, leak-free seal and the fastening ring prohibits any inclination the pipe may have to slide out of position adjacent the pipe end point lip  71  (see  FIG. 3 ) inside the pipe fitting  12 . 
       FIGS. 12-18  illustrate an alternative embodiment of the present invention. In this embodiment, the first radial housing element  40  of the fitting  12  is substantially the same as described above. Further, as shown in  FIG. 12 , the fitting  12 , sealing members  14 ,  16 , release pusher  20  and fastening ring  18  are similarly present. However, the second radial housing element  42  includes a front wall segment  72  that does not have a top angled guiding surface. Rather, the front wall segment  72  of the second radial housing element  42  extends radially outwardly and into the fitting inner wall  13 . As such, the second radial housing element  42  includes the inner wall surface.  13  for engaging the circumferential base  52  of the fastening ring  18 , as well as a surface  74  for engaging the circumferential base  92  of a snap ring  90 . Surface  75  provides a guiding surface for the release pusher  20  as it is pushed axially inwardly of the fitting in order to depress the fastening ring teeth so as to allow removal of an inserted pipe member, for example. As shown in  FIGS. 17 and 18 , the snap ring  90  includes a fastening ring-engaging surface  94  and a release pusher engaging surface  96 , and is positioned in place in the fitting when the release pusher  20  is snapped or popped into engagement with the retaining lip  34  of the fitting  12 . The snap ring  90  can comprise a spring steel formulation. Further, circumferential base  92  can extend from the horizontal axis H of the snap ring  90  at an angle I of between approximately 6.5 degrees and approximately 50 degrees. In a particular embodiment of the present invention, angle I is approximately 40 degrees. 
     While the fastening ring  18  is shown in  FIG. 12  as being a split ring, the fastening ring in this embodiment of the present invention can also be an integral ring that is not split. As such, and given the lower profile of the front wall segment  72  of the second radial housing element  42 , the fastening ring can be more easily inserted into the second radial housing element without as much initial deformation as that associated with the embodiment of the present invention shown in  FIGS. 1-5 , for example. 
     In the embodiment of the present invention with the snap ring  90 , the snap ring can be provided with a split similar to that provided in fastening ring  18  in  FIG. 1 . After placing the fastening ring into the second radial housing element, the support snap ring gland  90  can be compressed with a tool using fixture points (not shown) similar to that shown for the fastening ring  18  of  FIG. 10 , and then positioned within the second radial housing element  42 . The compression of the supporting snap ring gland is released, and the ring returns to its original manufactured size, thereby acting to retain the fastening ring in position. Next, the release pusher  20  can be pushed into place such that the ledge back wall  29  removably engages the lip member  34  of the fitting  12 . 
     An alternative embodiment of the push connect joint assembly  110  of the present invention is illustrated in  FIGS. 19-31 . As shown in  FIGS. 19 and 20 , elements of the joint assembly as shown include: a fitting (i.e., fitting body member)  112  having an inner wall  113  and outer wall  115 , a fastening ring  118 , two substantially identical sealing members  114 ,  116  (which can be optionally lubricated), a sealing member support ring  117 , a spacer member  119  and a release pusher member (also referred to as a release pusher or a release push cap)  120 . The sealing member support ring and fastening ring together provide one embodiment of a packing arrangement for the present invention, and each has an internal diameter that allows for smooth and snug engagement of a piping or tubing element external surface  124 . The fitting  112  is substantially hollow with a pipe receiving opening  200  therein. 
     As shown in  FIGS. 20 ,  21  and  23 , the fitting  112  is formed with a first radial housing element  140  to house sealing members  114  and  116  and a second radial housing element  142  to house the sealing member support ring  117 , the fastening ring  118  and the spacer member  119 . The sealing members can be housed so as to substantially abut one another within the first radial housing element  140 . The sealing member support ring  117 , the fastening ring  118  and the spacer member  119  can be housed so as to substantially abut one another within the second radial housing element  142 . The sealing member support ring  117  and O-ring member  116  can abut one another when installed, or there can be a slight gap in between these members when installed. 
     The first radial housing element  140  is formed by a first housing back wall segment  144 , the fitting inner wall  113  and a housing separator segment  146 . The second radial housing element  142  is formed by the housing separator segment  146 , the fitting inner wall  113  and a housing front wall segment  148 . In one embodiment, the radius of the second radial housing element  142  is slightly larger than the radius of the first radial housing element  140 . 
     In one embodiment, the interior diameters of the sealing member support ring  117 , fastening ring  118  (as measured to the teeth  121  and not the ring cylindrical base), spacer member  119  and sealing members  114 ,  116  are substantially the same, and the interior diameters of the fitting  112  and the release pusher  120  are substantially the same. Further, the interior diameters of the sealing member support ring  117 , fastening ring  118 , spacer member  119  and sealing members  114 ,  116  are slightly less than that of the fitting  112  and release pusher  120  so as to facilitate proper operation of the present invention. 
     As shown in  FIGS. 19 through 22  and  25  through  26 , the sealing member support ring or member  117  has a circumferential base  124 , a sealing member-engaging surface  127  and a fastening ring-engaging surface  126 . Further, circumferential base  124  can extend from the horizontal axis J of the sealing member support ring  117  at an angle K of between approximately 6.5 degrees and approximately 50 degrees. In a particular embodiment of the present invention, angle K is approximately 37 degrees. In one embodiment of the present invention, the sealing member support ring  117  includes a first circumferential end point  128  and a second circumferential end point  129  that do not connect and thereby form a slit  125 . Each of the first and second end points  128 ,  129  includes a facing edge, and each facing edge is not aligned with the radial axes of the support member. For instance, line A-A in  FIG. 28  shows radial axes of the support member  117 , and this line does not extend through or otherwise align with the facing edges of the end points  128 ,  129  of the support ring member  117 . In an alternative embodiment, the end points  128  and  129  can include facing edges that are aligned with radial axes of the sealing member support ring  117 . The slit  125  allows the sealing member support ring  117  to be manually pinched and compressed. When compressed, one circumferential end point can overlap the second circumferential end point so that the sealing member support ring can be easily inserted into a fitting. The overlapping capability is facilitated by the facing edges of the end points  128 ,  129  being unaligned with radial axes of the support member. 
     As shown in  FIGS. 19 and 27  through  29 , the fastening ring  118  can be a split ring member having a circumferential base  132  and two circumferential end points  130  and  131  that do not connect. The gap formed between the non-connecting circumferential end points  130 ,  131  allows for the fastening ring to be easily compressed for insertion into a fitting. As shown in  FIG. 28 , the first  130  and second  131  end points include facing edges that extend substantially radially outwardly along respective radial axes of the ring. Line  28 - 28  illustrates different axes extending radially outwardly from the center axis of the fastening ring. The arrangement of the end points  130 ,  131  and their facing edges as shown facilitates ease of operability while maintaining overall strength of the fastening ring  118 . 
     The fastening ring can further include fixture points for handling and compressing the fastening ring. In one embodiment of the present invention, the fixture points are provided at the split end so that a tool designed to hold the fastening ring at the fixture points can more easily handle and compress the fastening ring in order to assist with assembly or disassembly. Once compressed, the fastening ring is easily insertable into the second radial housing element  142  of the fitting  112  by releasing the compression hold on the fastening ring, thereby allowing the fastening ring to expand such that the circumferential base engages the walls of the second radial housing element. The fastening ring can be removed from the second radial housing element in reverse manner. In one embodiment of the present invention, the split fastening ring  118  has a diameter that exceeds the diameter of the split sealing member support ring  117 . No wrenches, solder, welding, glue and/or twisting and turning the elements are required to form or disengage a connection. 
     As further shown in  FIGS. 19 and 27  through  29 , the fastening ring  118  includes a substantially cylindrical base  132  that has a plurality of bifurcated or square edged teeth  121  extending inwardly from and along the base of the ring  132 . As shown in  FIG. 27 , the teeth  121  of the fastening ring  118  can extend at an angle M from the horizontal axis L, wherein M ranges from approximately 39 degrees to approximately 68 degrees. In one embodiment of the present invention, angle M is approximately 56 degrees. These angles are measured when the teeth are at rest position and are not stressed by the insertion of a pipe. In one embodiment, each tooth has a squared-off outer edge comprising a left edge, a right edge and a bottom edge. The top edge of each tooth is integrally connected to the circumferential base  132  of the fastening ring  118 . The number of teeth can readily vary in number and size. 
     As shown in  FIGS. 19 and 30  through  31 , the packing arrangement may further include a spacer member  119 . The spacer member is substantially cylindrical in shape and includes a circumferential base  133 , a fastening ring-receiving end  137 , an exterior surface  138 , an interior surface  134  and a top end  139 . Furthermore, the spacer member can be a split ring member having a circumferential base  133  and two circumferential end points that do not connect, similar to that of the fastening ring  118  shown in  FIG. 28 , for example. The gap formed between the non-connecting circumferential end points allows for the spacer member to he easily compressed for insertion into a fitting. As shown in  FIGS. 21 and 22 , once inserted into the second radial housing member  142 , the exterior surface  138  of the spacer member  119  is flush with the fitting interior wall  113  and the fastening ring-receiving end  137  is flush with the circumferential base  132  of the fastening ring  118 . Furthermore, the top end  130  of the spacer member  119  is adjacent to and flush with the housing front wall segment  148  of the second radial housing element  142  (see  FIG. 23 ). The spacer member  119  can comprise a spring steel formulation in one embodiment of the present invention. Further, the spacer member may be a separate piece as shown in  FIG. 19 , or it may be integrated with the fastening ring such that these two elements form a single, monolithic piece in the fitting packing arrangement. When the spacer member is integrated into the fastening ring  118 , it forms a fastening ring crown that operates similarly to the spacer member. 
     The release pusher  120  is substantially cylindrical and hollow and includes an external tip  122  at the fastening ring engaging end thereof, as shown in  FIG. 24 . The release pusher  120  also includes a radially outer ledge segment  135 , a ledge back wall  136 , and a second outer wall segment  150 . The pusher can comprise an injection-molded plastic or a metal material such as brass, for example. When pressure is applied on the back side  151  of the release pusher  120 , the external tip  122  can engage the inside surface of the fastening ring teeth  121  and the ledge back wall  136  can removeably engage the housing front wall segment  148 , as shown in  FIG. 22 . Once the release pusher  120  is inserted into the fitting  112 , the radially outer ledge segment  135  provides for flush engagement with the interior surface  134  of the spacer member  119 . The diameter of the release pusher  120 , as measure to the exterior surface of the radially outer ledge segment  135 , can be slightly less than the diameter of the spacer member  119 , as measured to the interior surface  134 , in one embodiment of the present invention. 
     In one embodiment of the release pusher of the present invention, the second outer wall segment  150  comprises a linear segment front the radially outer ledge segment  135  to the external tip  122 . As shown in  FIG. 24 , the second outer wall segment  150  extends linearly at a first angle O from the horizontal axis P to the external tip  122 . The angle ranges from approximately 8 degrees to approximately 73 degrees. 
     In operation, the fitting  112  of the present invention is provided and one or more sealing members  114 ,  116  are inserted into the first radial housing element  140 , as shown in  FIG. 21 . Next, the sealing member support ring  117 , the fastening ring  118  and the spacer member  119  are inserted into the second radial housing element  142 , and release pusher  120  is snapped into engagement with fitting  112 . When a pipe  70  is inserted, it travels through the release pusher  120  into the pipe receiving cavity  200  of the fitting  112 , engaging the fastening ring  118  and the one or more sealing members  114 ,  116 . The sealing members provide a strong, leak-free seal and the combination of the sealing member support ring  117 , the fastening ring  118  and the spacer member  119  prohibits any inclination the pipe may have to slide out of position. 
     The angles described herein will be understood to be exemplary and provided as embodiments associated with proper working operation of the present invention. For example, the angles of the top surfaces of members  46  and  48  contribute to the stability of the present invention as well as the easy manipulation of its component parts. Further, it will be appreciated that, in one embodiment of the present invention, the members of the push connect joint assembly are formed through hydroforming processes. 
     The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the claims of the application rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
