ABSTRACT:
A captive sealing assembly including a sealing mass of deformable material and first and second retainers on opposite sides of the sealing mass. The sealing assembly is adapted for use in a seal groove at least partially defined by first and second surfaces to be sealed. The first and second surfaces and the retainers cooperate to define a completely enclosed seal cavity of variable volume for the sealing mass. The retainers are resiliently loaded in a direction to compressively load the sealing mass.
