Abstract
An inventive valve stem seal assembly includes a seal body bonded to a metal retainer without the need for a separate retaining ring or a garter spring. Compressive radial force between the seal body and a corresponding engagement surface of a valve stem is provided by an end wall of the retainer, and in particular, tangs which extend generally longitudinally away from the end wall. The seal body envelops the tangs, and the tangs selectively flex when a valve stem is inserted through an aperture of the seal body.
