Abstract

An elastomeric seal (32) having an antiextrusion device (10) molded integrally into or onto the low pressure side of the seal. The antiextrusion device of a corrugated strip (10) into an elastomeric seal (32). One embodiment of the invention has the strip positioned with the midplane of its corrugations normal to the mating seal surfaces and parallel to the midplane of the seal groove. Another embodiment of the invention has the midplane of the corrugations canted within the seal. The antiextrusion device is applicable to annular seal rings, linear seals, or seals of more complex configuration (36).
