Abstract
A valve stem seal assembly has an elastomeric seal with first and second radially inwardly directed sealing lips that are in intimate sealing contact with a valve stem. The assembly also has a metal seal retainer with a first metal seal retainer portion that has a surface axially slanted inward and downward from a top of the elastomeric seal. This slanted portion forms a metal frustoconical foundation with a second metal seal retainer portion that directly radially extends from the metal frustoconical foundation. The axially slanted inward surface of the metal retainer is directly radially outward from the radially inwardly directed first sealing lip.
