Unique gasket material with the highest flexibility at high temperatures, manufactured from a high-quality fibre and filler compound.
A high temperature-resistant HNBR matrix is used as the binding agent. Suitable for use in oils, water, steam, gases, salt solutions, fuels, alcohols, weak organic and inorganic acids, hydrocarbons, lubricants and refrigerants.

Optimum combination of synthetic fibres bounded in a high temperature-resistant HNBR matrix.

Function and durability
The performance and service life of KLINGER gaskets depend in large measure on proper storage and fitting, factors beyond the manufactor’s control. We can, however, vouch for the excellent quality of our products. With this in mind, please also observe our installation instructions.

pT diagram
The Klinger pT diagram provides guidelines for determining the suitability of a particular gasket material for a specific application based on the operating temperature and pressure only. Always refer to the chemical resistance of the gasket to the fluid.
