Paper

 

Some well-known gasket-sheet grades include Flexoid, Klinger, Novus, Tesnit, Frenzelit and Garlock materials.

For example, Flexoid is the classic brown oil-resistant gasket paper frequently used for automotive, gearbox, pump and general engineering gaskets. It is available in thin gauges and is easy to die-cut.

For something more demanding, modern compressed fibre materials such as Klingersil C-4430 use aramid fibres with an NBR binder and provide considerably better temperature and pressure capability.
