Patent ID: 7922179

Claim:
A cast-in-place gasket for an associated pipe joint, the gasket being mounted to a first associated pipe and adapted to provide a seal between the first associated pipe and a second associated pipe, said gasket comprising: a gasket body formed into an annulus from a resilient material; a first sealing head and a second sealing head protruding from said body in an axially rearward and radially inward direction, said first sealing head being axially spaced from said second sealing head, each of said first sealing head and said second sealing head including a sealing surface; a first mounting foot and a second mounting foot protruding from said body in a radially outward direction, at least one of the first and second mounting feet having a radially outer axial dimension that is larger than a radially inner axial dimension for securing the gasket within a casting material of the first associated pipe, said first mounting foot being axially spaced from said second mounting foot; an open annular cavity defined in said body between said first sealing head and said second sealing head; a first lip protruding from said body proximal to a base end of said first sealing head and extending in an axially forward and radially inward direction; a second lip protruding from said body proximal to an end of said sealing surface of said second sealing head and extending in an axially rearward and radially inward direction; and wherein said first lip and said second lip cooperate to inhibit the flow of an associated casting material from contacting said sealing surfaces of said gasket during casting of the associated first pipe.
