Gasket made from aramide fibres FJ 2639

FJ2639 is an asbestos-free gasket material. It consists of aramide fibers and other substances that are resistant to high temperatures and are processed with high-grade elastomers under elevated pressure and temperature.

On the one hand, this economical gasket material is conformable and flexible, which ensures adequate sealing even with low surface pressure. On the other hand, it provides adequately high stress resistance coupled with good gas sealability. In addition FJ2639 is resistant to solvents, oils, fuels, water, and many other media.


  • for sealed joints that are subject to moderate thermal and mechanical stress
  • for lightweight components and flanges
  • for apparatus, transmissions, pumps, sanitary fittings
  • for sealing lightweight components with comparatively low surface pressure, e.g. transmissions, valve covers, oil pans and covers in IC engines.

Thanks to its physiological harmlessness FJ2639 can be used especially also in the drinking water and foodstuff sector.
