James Walker Chieftain X Gaskets

Graphite reinforced with aramid fibre and nitrile binder
Chieftain X is a high performance BS7531 Grade X sheet jointing, based on graphite reinforced with aramid fibres with a nitrile (NBR) binder, and complies with the test requirements of BS7531 Grade X. The unique blend of aramid fibres and graphite results in a gasket material with exceptional leakage resistance and residual stress levels.

Product features
The material is supplied with an anti-stick finish to both surfaces as standard, which minimises adhesion of the gasket to flange surfaces even at elevated temperatures, resulting in being easy to remove in a short time.
