MOLDED LIP SEAL WITH POLYTETRAFLUORETHYLENE LINER AND METHOD FOR MAKING THE SAME A shaft seal (and method for making the same) of the type having an annular elastomeric body, a molded lip, and the molded lip having a liner of sintered polytetrafluoroethylene bonded thereto. The elastomer is molded simultaneously with the polytetrafluoroethylene liner being formed and bonded to the elastomer.
