Abstract
A pipe sealing gasket is shown which is designed to be received within a raceway provided within a socket end of a female bell plastic pipe end which is assembled with a mating male spigot pipe end to form a plastic pipe joint. The raceway in the female bell plastic pipe end is preformed during manufacture and the gasket is installed thereafter. The gasket has a rubber body portion which is reinforced by a hard corrugated ring-shaped insert. The hard corrugated ring-shaped insert acts to prevent extrusion of the gasket during a variety of pressure conditions as well as preventing displacement during field assembly.
