ABSTRACT OF THE DISCLOSURE A high pressure oil seal unit comprising an elastomeric sealing lip portion and a casing portion made from a rigid material and having a mounting flange, a radially extending, offsetting flange, and an annular inner mounting bead formed by folding at least two thicknesses of the casing material upon each other so as to form first and second inclined flange portions connected to each other by a bight portion. One of the thicknesses terminates in an edge portion with the bight portion presenting a rounder exterior surface portion directed generally toward the sealed region and the inner diameter of the seal. The sealing lip portion has air and oil side surfaces meeting each other along a circumferential locus to define a seal band, and has another portion bonded to and completely surrounding an inner margin of the radial casing flange and the exterior surfaces and edge portion of the material thicknesses forming the bead, to provide a bonded area adapted to resist failure under the application of high pressure.
