High Temperature Gasket Material

We stock and supply high temperature gasket material. The following materials are available:

  • Non-Asbestos Fibre Jointing
  • Ceramic Fibre (such as Firefly)
  • Blended PTFE
  • Nitrile Rubber
  • Silicone Rubber
  • Tang Graphite (with and without steel inserts)

Rubber materials, such as silicone, can function up to 300ºC. Graphite is commonly used in high-temperature, high pressure applications and where steam is present. Ceramic fibre can operate up to 1000ºC, however it is very hard and brittle.

For gasket material temperature ratings and charts please see our article on operating temperature.
