PSM Eyelet Gasket

Characterising & main applications

  • Unique Anti-stick coating – no unnecessary cleaning of flanges.
  • High blow out resistance compared to non-metallic gaskets.
  • No possible leakage through gasket body.
  • Excellent high temperature vacuum seal.
  • Tanged graphite combined with metal eyelet provides a high resistance to graphite extrusion preventing contamination of the line.
  • Broad chemical resistance.
  • Low emission seal.
  • Maximum temperature 450°C when exposes to air /oxygen – higher temperature possible in oxygen-free or reducing environments.
  • Seals poor condition flanges due to graphite sealing while the eyelet material can be suited to the process media.
  • 316 and galvanised carbon steel are standard eyelet grades.
  • Tanged insert prevents excessive graphite relaxation under high temperature / pressures.




Combines the advantages of PSM with a metallic eyelet at the gasket’s inner diameter.
