Abstract
A sealing ring for a seal assembly used in oil field equipment including an elastomeric body and a reinforced face. The reinforced face is of molded polytetrafluoroethylene and is integral with the elastomeric body to provide improved pressure capability for the seal without the need for backup rings. The elastomeric body is formed to have a waisted cross section with a narrower portion in the middle and a wider portion at each end. The wider ends provide multiple sealing surfaces and allow fewer rings to be used.
