Technical data
Klinger cold/hot compression
With this test method developed by Klinger you can evaluate the cold/hot compression of a gasket in cold and
hot condition. Unlike the method acc. to DIN 52913 and BS 7531, the surface load is kept constant during the complete
test so that the gasket is exposed to much tougher conditions.
The thickness decrease at an ambient temperature of 23°C and at heating up to 200°C is measured.
The indicated thickness decrease at 200°C refers to the thickness obtained after loading at 23°C.

Rings and other finished gaskets
These gaskets are available in any size and corresponding sheet thicknesses, also edged and PTFEcovered.
The standard surface finish of the material is such that the surface has an extremely low adhesion. On
request, graphite facings and other surface finishes on one or both sides are also available.
Function and durability
The performance and 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.
