Polymeric pipe fitting and gasket assembly and sealed polymeric pipe apparatus formed therewith

摘要

A polymeric pipe fitting assembly for joinder with a polymeric pipe section without using adhesives or other chemicals comprises a polymeric fitting and an elastomeric gasket formed as a unit, preferably by molding. The fitting has a main body portion with a pipe-receiving socket portion at one end. The gasket has a first axial portion molded in intimate sealed surface engagement interiorly within the socket portion and a second integral axial portion projecting axially from the socket portion. The axial portions of the gasket form a continuous interior wall surface for receiving a polymeric pipe section in peripheral surface contact with an exterior surface of the pipe section. The second axial portion of the gasket is encircled by a mechanical clamping device for sealing the gasket against the exterior of the pipe section.
