High Temperature Gasket

The High Operating Temperature spiral wound gasket utilises high recovery, heat treated Monel spiral windings combined with a oxidation inhibited graphite with a high temperature oxidation shield on both inside and outside diameters.
The Mica filler gasket was developed to overcome the problems associated with leakage due to the deterioration of the gasket filler materials at high temperature.
- For use up to 1,000 Centigrade
- Contains no asbestos materials
- Various metallic winding materials are available
- Available with external compression gauge Inner-Ring Type, Outer-Ring Type,
