摘要: A gasket retention system and flange coupling has a ring gasket that disposes in seal seats on opposing flanges. One or more retainer tabs extend from an outer periphery of the ring gasket. Preferably, the ring gasket defines a slot on the outer periphery, and the retainer tab affixes with an interference fit in the slot to be held therein. The retainer tab defines a transverse opening therethrough. When the ring gasket fits into the seal seat of one of the flanges, the transverse opening of the tab fits onto a fastener affixed in a pre-drilled hole in the face of the flange.
