EXTRUSION RESISTANT GASKET FACE SEAL

摘要

A seal assembly for a fluid coupling includes: (a) a generally planar, substantially rigid seal retainer (42) with opposed first and second faces, having an annular first groove (48) formed in the first face; (b) a first resilient seal (56) disposed in the first groove (48); and (c) an annular first backup ring (58) positioned radially outboard of the first resilient seal (56) and secured to the first resilient seal (56), wherein the first backup ring (58) is substantially harder than the first resilient seal (56).
