Properties and application
Top quality universal gasket material - specially reinforced - for use at very high pressures, high temperatures and surface stresses. Especially convenient for use at temperature and pressure fluctuations and mechanical vibrations. Due to special metal reinforcement assures also high protection against blow out.
Material combines high torque retention, good chemical resistance, excellent sealability and outstanding thermo-mechanical properties.
Suitable for sealing of hot water, steam, oils, fuels, non-aggressive chemicals and many other media.
