Material Composition:
Factors affecting on the gasket Areas of application
Dimensions of standard sheets :
Chrysotile asbestos fibre, Mineral Fibre, Natural Rubber and NBR.
General properties and applications :
To seal off motor oil, carburetor mixtures, hydraulic fluids, low temperature oils, steam, alkalies and water/antifreeze and
water/anticorrosion mixtures, highly suitable for internal combustion engines, compressors.
The suitability of a gasket material for an
application is dependent upon a multiplicity of
factors as shown in the above digram. Max.
temperature and pressure values can not define
the suitability for application. It is always
advisable to consider these factors when
selecting a material for a given application .
This area refer , the gasket material is normally suitable subject to
chemical compatibility.
This area refer, the gasket material may be suitable but a technical
support is recommended.
This area refer, do not install the gasket without technical evaluation.

All information and recommendations given in this brochure are correct to the best of our knowledge. However, in view of the
wide variety of possible installation and operating conditions one cannot draw the final conclusion in all application cases
regarding the behaviour in a gasket joint. Therefore, information can only serve as a guideline
