ABSTRACT An oil seal unit for disposition between portions of mating parts having opposed end face sealing surfaces and which are urged together in fluid-tight relation, one of said mating parts also having a shank portion adapted to extend axially through an associated seal unit. The oil seal unit comprises, in combination, a casing unit having an axially extending centering flange portion and a radially extending bonding flange portion with opposed end face surfaces and an inner margin portion, and an elastomeric, seal body bonded to said casing unit. The body has radially inner, outer and intermediate seal body portions, the outer elastomeric seal body portion including at least one substantially continuous sealing rib overlying one of the casing end face surfaces and at least one substantially continuous rib overlying the other of the casing end face surfaces. The radially inner portion of the said elastomeric seal body includes a radially extending web terminating in a radially inner, axially extending web surface portion defining an opening through which the shank portion of the one mating part may extend, the web also engaging the shank portion of the one mating part so as to support the seal relative to the one mating part. The intermediate seal body portion includes an element adapted to be deformed into snug fluid-tight sealing engagement within a recess defined in part by the seal unit and in part by the opposed end face sealing surfaces.
