Chieftain® X

Our premium grade universal sheet jointing.

  • Valves
  • Water

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.

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 reduced removal time.

  • A soft cut gasket for extreme applications in general industry
  • Media compatibility with oils, fuels and hydrocarbon compounds
  • Suitable for use in cryogenic conditions
  • Can be used on the majority of flange specifications including ASME, API, EN, BS and DIN
  • Excellent resistance to acids, alkalis, solvents, refrigerants, water and steam

  • Maximum temperature: +450°C (+842°F)
  • Minimum temperature: -200°C (-328°F)
  • Maximum pressure: 10 MPa/100 bar (1450 psi)
