The gasket uses expanded graphite tape as the filler material which provides superb sealability even under severe conditions such us high temperature, high pressure, cryogenic temperatures, heat cycles, temperature cycles and so on.

Feature
1. Sealing, especially gas sealing, is superior to that of asbestos gaskets.
2. Little deterioration of the filler material at high temperatures, outstanding long-term sealability even under high temperatures and high pressures.
3. Sealing remains outstanding even under servere conditions such as pressure fluctuations and heat cycles.
4. Excellent sealability is maintained making it possible to apply this for corrosive fluids by selecting the appropriate materials.
5. Outstanding sealing even at cryogenic temperatures.
