ABSTRACT:
Improved gasket material and method for use in sealing various flanged apparatus, such as found in distillation columns, glass lined vessels and transformer radiator flange seals. The gasket material comprises a cylindrical core of elongated polytetrafluoroethylene (PTFE) contained within a tight wrap of high strength film or films. The gasket material has the exceptional operational properties of PTFE, can be designed for specific situations, and has superior resistance to cold flow or "creep" which distorts most PTFE seals under heavy unconfined compression.
