ABSTRACT:
A gasket for a socket-spigot connection between a socket end and a spigot end of two pipes to be connected is made of a material stable as to its shape and adapted to carry at its inner radial side at least one resilient sealing ring and at its outer radial side at least one other sealing ring. The gasket has an outer diameter equal to or slightly less than the inner diameter of the socket and an inner diameter equal to or greater than the outer diameter of the spigot. The gasket has a radial inner ring groove and a radial outer ring groove, the radial inner ring groove being constructed and arranged to receive one of the seal rings to provide a pressure seal engagement between the one seal ring and the outer surface of the spigot, the radial outer ring groove being constructed and arranged to receive another of the seal rings to provide a pressure seal engagement between the other seal ring and the inside surface of the socket.
