ABSTRACT:
Improved O-ring gasket material and method for use in sealing various apparatus, such as fluid conduits for heat exchange apparatus, is provided. The gasket material comprises a cylindrical core of elongated polytetrafluoroethylene (PTFE) contained within a tight wrap of high strength film. The gasket material has the exceptional operational properties of PTFE, while being resistant to cold flow or "creep" which distorts most PTFE seals under heavy unconfined compression.
