ABSTRACT:
A pipe gasket is shown for use in forming a joint made up of an outer pipe having an annular groove therein for receiving the gasket and an inner pipe inserted within the outer pipe. The gasket includes a body formed from a resilient material having an interior and an exterior. The interior of the body includes a first portion formed of a hard, relatively high durometer material which is initially contacted by the inner pipe and a second portion formed of a relatively lower durometer, more flexible material. The second portion includes an inwardly extending projection which forms a primary sealing surface with respect to the inner pipe when the inner and outer pipes are assembled. Because the entry region initially contacted by the inner pipe is formed of a higher durometer material, the gasket tends to securely maintain its position within the outer pipe groove during the installation of the inner pipe.
