Abstract
A cast-in-place gasket is provided for an associated pipe joint. The gasket is mounted to a first associated pipe and adapted to provide a seal between the first associated pipe and a second associated pipe. The gasket includes a gasket body formed into an annulus from a resilient material. A first sealing head and a second sealing head protrude from the body in an axially rearward and radially inward direction. The first sealing head is axially spaced from the second sealing head. Each of the first sealing head and the second sealing head include a sealing surface. A first mounting foot and a second mounting foot protrude from the body in a radially outward direction. The first mounting foot is axially spaced from the second mounting foot. An open annular cavity is defined in the body between the first sealing head and the second sealing head. A first lip protrudes from the body proximal to a base of the first sealing head and extends in an axially forward and radially inward direction. A second lip protrudes from the body proximal to the sealing surface of the second sealing head and extends in an axially rearward and radially inward direction. The first lip and the second lip cooperate to inhibit the flow of an associated casting material from contacting the sealing surfaces of the gasket during casting of the associated first pipe.
