Abstract
An oil seal, the combination thereof with a housing bore, and a method for installing the oil seal. This invention relates to applications where minimal radial force may be exerted against a housing bore and where the seal must be positively retained in the bore. The oil seal includes a shell having a locking member deformable radially outwardly, and an elastomeric sealing element bonded to the shell and including a face gasket for providing an O.D. seal when the locking member is deformed outwardly into an annular retaining groove in a housing bore. The seal is positively retained in the bore while exerting only minimal radial force against the bore while using less expensive cold rolled steel for the shell as contrasted to the more expensive spring steel required for snap-locking shells.
