Abstract

A sealing gasket is shown which is used to seal the belled end opening of a female ductile iron pipe to a mating male pipe having an interior surface and an exterior surface. The sealing gasket has an annular gasket body made of a resilient elastomeric material which is bonded to a hard plastic reinforcing band. The annular gasket body is installed within a raceway provided in the mouth region of the female ductile iron pipe so that an outer circumferential region forms a seal with the female pipe mouth region and an inner circumferential region forms a sealing surface for the exterior surface of the mating male pipe. The reinforcing band has a circumferential body which is made of a synthetic polymer which has a greater hardness than the elastomeric material of the remainder of the gasket body.
