Camprofile serrated gasket 9588


The Camprofile serrated gasket 9588/P has a concentrically machined serrated profile from a base plate and a layer of graphite (purity > 98 %) on both sides, each with 0.5 mm standard thickness (thicker layers on request). The gasket is easy to handle and particularly appropriate for flanges and flange-like connections in chemical and petrochemical industry, in power plants and nuclear power plants, etc.


  • Great pressure resistance
  • Good chemical, thermal and mechanical resistance
  • Very low minimum surface pressure
  • Designed for very sophisticated applications
  • Outstanding performance cycling applications

Recommended surface roughness Rz < 25 µm. For greater roughness up to max. 50 µm the thickness of graphite layer should be increased. After first warm-up, retightening of bolts is recommended (only without system pressure). This will insure optimum surface pressure.

The surface layer material can only be used once. The serrated gasket can be reused several times if not damaged.
