SEAL FOR SENDING UNIT

摘要

An oil seal unit for disposition between mating parts having opposed end face sealing surfaces. The seal unit has a casing with a radial flange having opposed end face surfaces and an inner margin portion. An elastomeric seal body with radially inner, outer and intermediate body portions is bonded to the casing. The seal body includes a radially space apart, continuous circular sealing ribs over lying each face of the casing; the seal body also has a radially inner portion defining an opening through which the shank portion of the mating part extends. The intermediate part of the seal body includes a collar element which deforms into snug fluid-tight sealing engagement within a recess defined in part by the seal and in part by portions of the mating parts.
