ABSTRACT:
An end portion of a pipe fitting or coupling member is provided. The member has a central longitudinal axis, a mouth at its very end, and an annular groove for receiving a gasket. The groove presents a first end wall spaced from and axially facing the mouth. The end wall has a radial inward end and a radial outward end. A radially inwardly facing axially extending bottom wall extends substantially parallel to the longitudinal axis towards the mouth and extends from the radial outward end of the first end wall. The bottom wall terminates at a second wall axially facing the mouth. The second wall extends radially outwardly from the bottom wall has a radial inward end and a radial outward end, the radial inward end of the second wall connected to the bottom wall. The radial outward end of the second wall terminates further from the longitudinal axis than the bottom wall at a radially facing wall which extends axially away from the bottom wall towards the mouth for part of its extension and then being bent over to extend towards the longitudinal axis. A gasket is captured in the groove and has a central longitudinal axis and axially spaced opposing ends interconnected by an outer wall. One of the opposing ends of the gasket engages the first end wall of the groove and the other end of the gasket comprises an offset portion for being received between and in intimate contact with the second wall and radially facing axially extending wall bent over for part of its extension.
