ABSTRACT:
A gasket assembly suitable for sealing between two pipe members in a high pressure pipeline includes an annular gasket body made of a resilent material. The body terminates radially inwardly in a leading lip and a pressure actuated sealing lip. The leading lip has a pipe centering and cleaning face and a compression sealing face. An enclosed annular groove is provided in the gasket body with an annular retaining ring being provided in the groove. The ring is made of a material harder than the gasket body and functions to retain the gasket body in the pipe groove.
