Beschreibung
Zusammenfassung:	A tool for making a service pipe coupling or joint for use in fluid distribution systems, the coupling or joint utilizing a plastic pipe, a flare-type coupling nut for coupling the plastic pipe into a distribution system, the coupling nut cooperating with a tubular body member which may be another pipe, a valve, or other fitting. The plastic pipe has its end portion cold flared beyond its elastic limit or memory by the tool into an annular upset bead-like portion terminating in an inwardly turned lip, the annular upset bead-like portion trapping the plastic pipe axially with respect to the coupling nut. The application of the tubular body to form the coupling or joint further forms the bead-like flare to provide a seal and packing and to increase the resistance of pipe pullout from the joint.
