ABSTRACT:
A molded resilient ring seal with support rings mold bonded or bonded and connected to both ends. The molded resilient material portion of the seal utilizes unique contouring to reduce internal resilient material stresses during use, enabling the seal to seal higher pressures at elevated temperatures for longer periods of time. A number of support ring configurations are also disclosed, which further enhance sealing ability of the resilient material.
