All data quoted above
are based on years of experience in production & operation of
sealing elements, in view of the wide variety of possible
installation & operating conditions one can not draw final
conclusion in all application cases regarding the behavior in gasket
joint. The data may not therefore, be used to support any warranty
claims.
