Characteristic & main applications

KLINGER®SLS is available in the unique AS (anti stick) or G configuration.

The steel foil gives improved handling and load-bearing characteristics.

The excellent conformability of graphite means that the material is suitable for applications where bolt load is limited or flanges are damaged.

It is ideal for use in the pulp and paper, chemicals and steam industries.



Pure exfoliated graphite with a stainless steel foil reinforcement.

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.

1. In area one, the gasket material is normally suitable subject to chemical compatibility.
2. In area two, the gasket materials may be suitable but a technical evaluation is recommended.
3. In area three, do not install the gasket without a technical evaluation.

Function and durability

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