ABSTRACT:
An improved face seal assembly (10) is provided to prevent fluid leakage between assembled structural components (12), (14) or the like, such as housing components of a fluid control valve or the like. The face seal assembly (10) comprises a metal seal ring (16) defined by a rigid seal base (22) having generally parallel axial side faces (24), in combination with a pair of deflectable seal legs (26) extending generally radially from the seal base as axially diverging continuation of said side faces. The seal ring (16) is sandwiched coaxially between a pair of film gaskets (18) of a selected seal material, preferably such as a Teflon coated polyimide film. The resultant seal ring and gasket stack forms the face seal assembly (10) and is interposed between assembled housing components or the like to deflect the seal legs (26) toward each other into substantially coplanar relation with the axial side faces (24) of the seal base (22).
