Abstract
An annular seal assembly for forming a seal between two annular surfaces. The seal assembly includes an annular base including a sealing surface. The seal assembly also includes a pair of spaced apart rims extending from the annular base opposite the base sealing surface and in opposite directions, the rims also including sealing surfaces. The base is elastically deformable and the rims are elastically deformable relative to the base to effect a self-energized seal between the two annular surfaces.
