Abstract:
A resilient, annular pipe gasket for forming a seal between an annular rib provided on a radially outer surface of a first pipe and a radially inner surface of a second pipe, the rib having a radially outer surface, an axially forward side facing the end of the first pipe and an opposite axially rearward side, the first pipe and the second pipe being adapted to mate with a portion of the first pipe having the annular rib being received in the second pipe, the pipe gasket comprising:(a) a sealing base having a radially inner surface and a radially outer surface provided with sealing means;(b) a forward leg extending radially inwardly from an axially forward portion of the base; and(c) a flap extending radially outwardly and axially forwardly from a radially inner portion of the forward leg, the flap having a pipe engaging surface at a radially outer portion of the flap,wherein a first radial distance between the radially inner surface of the base and a radially outermost portion of the sealing means is greater than a second radial distance between the radially inner surface of the base and the pipe engaging surface of the flap, and wherein the first radial distance is less than a third radial distance between the radially inner portion of the forward leg and the pipe engaging surface.
