Abstract:
1. A tubular conduit, comprising: a thermoplastic tubular extrusion having a longitudinal axis; said thermoplastic tubular extrusion having a first end portion thereof which defines a relatively large diametrical extent for permitting said first end portion of said thermoplastic tubular extrusion to be connected to a first conduit connection having a relatively large diametrical extent; and said thermoplastic tubular extrusion having a second end portion thereof which defines a relatively small diametrical extent for permitting said second end portion of said thermoplastic tubular extrusion to be connected to a second conduit connection having a relatively small diametrical extent, wherein said relatively large diametrical extent is substantially larger than said relatively small diametrical extent; wherein said second end portion of said thermoplastic tubular extrusion is spirally coiled around said longitudinal axis of said thermoplastic tubular extrusion so as to define said relatively small diametrical extent of said thermoplastic tubular extrusion at said second end portion of said thermoplastic tubular extrusion.
