Soft-material gaskets are universal sealing elements with a large range of application in all branches of industry. They can be used within a temperature range of - 200 °C up to a maximum of + 550 °C. A suitable material should be selected depending on the medium, medium concentration, temperature and type of flange being used.
We produce flat gaskets in all commonly-used soft materials. See also the section "Materials commonly used" . As a general rule, thin gaskets are preferred to thicker ones.
The usual thickness of gaskets is 1; 1.5; 2 and 3 mm. PTFE gaskets should be used in the thinnest size possible due to cold flow.
The surface finish and evenness of the flange should determine the gasket thickness to be used. The better the flange surface, the thinner the gasket can be. Soft-material gaskets require only low seating surface pressure av, but can be more easily overloaded than metal gaskets or metal/soft-material gaskets, especially at narrower gasket widths.
