  Gasket materials / PTFE Products
Gasket material based on SBR-bound aramide fibres and anorganic fibres. Thanks to the swelling in oil and
fuels, it offers an excellent conformity with the flange at low surface loads.
The many, varied demands placed on gaskets
A common perception is that the suitability of a gasket for any given application depends upon the
maximum temperature and pressure conditions. This is not the case. Maximum temperature and
pressure values alone can not define a material’s suitability for an application.
These limits are dependent upon a multiplicity of factors as shown in the diagram below.
It is always advisable to consider these factors when selecting a material for a given application.
Selecting gaskets with pT diagrams
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.
Additional stresses such as fluctuating load may significantly
affect the suitability of a gasket in the application and must be
considered separately. Always refer to the chemical resistance of the
gasket to the fluid.
Areas of Application
(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
