Abstract:
1. A closure fitting for enclosing a portion of one or more carrier conduits between a first containment conduit section and a second containment conduit section, wherein the first containment conduit section has a proximal end portion terminating an open end, wherein the second containment conduit has a proximal end proximal terminating in an open end, and wherein the open end net of the first containment section proximal end portion is opposed to and spaced from the open end of the second containment section proximal end portion, the closure fitting comprising: (a) first cylindrical hollow body having a proximal end and a distal end; (b) a second cylindrical hollow body having a proximal end and a distal end, the proximal end of the second body being reversibly attached in fluid tight communication to the proximal end of the first body; (c) a first seal for sealing the first body to the proximal end portion of the first containment conduit and a second seal for sealing the second body to the proximal end portion of the second containment conduit, wherein (i) the first seat allows the first body to axially move with respect to the first containment conduit section, or (ii) the second seal allows the second body to axially move with respect to the second containment conduit section, or (iii) the first seal allows the first body to axially move with respect to the first containment conduit section and the second seal allows the second body to axially move with respect to the second containment conduit section; and (d) a third seal for reversibly sealing the proximal end of the first body to the proximal end of the second body; wherein the proximal end of one of the cylindrical bodies comprises a threaded end, and the third seal comprises a threaded nut for attachment to the threaded proximal end of the cylindrical body; whereby the closure fitting forms a cylinder which is capable of sealing in fluid tight fashion the proximal end portion of the first containment conduit to the proximal end portion of the second containment conduit, but whereby the first body and the second body are capable of being reversibly and axially separated from one another to allow access to one or more carrier conduits disposed between the first contaminant conduit section and the second containment conduit section.
