ABSTRACT:
A seal assembly is provided for retaining fluids within a sealed region defined in part by the seal assembly secured within an annular casing member and in part by a shaft extending axially through the seal assembly within the casing. The fluid seal assembly includes both a primary and a secondary lip arranged to facilitate easier, more reliable installation of the shaft therethrough. The primary and secondary lips are joined by a center section which is supported by a generally L-shaped support ring which extends to the casing to form the seal.
