*Temperature and pressure represent maximum values and should
not be used simultaneously. They are given only as guidance, since they depend
not only on the type of gasket material but also on the assembly conditions.
Very important factors are: thickness of material, nature of service medium
and type of flange and surface stress. Steam application requires special consideration.

All information data quoted in Technical Data Sheets are based
on years of experience in production and operation of sealing elements. However,
in view of the wide variety of possible installation and operating conditions
one cannot draw final conclusions in all application cases regarding the behavior
in a gasket joint. The data, may not, therefore be used to support any warranty
claims. Whenever there is any doubt, our staff will be pleased to assist you
in finding the optimum sealing solutions. Specifications are subject to change
