It widly used in many applications, such as heat exchangers, pumps, autoclaves, engines, valves and exhaust systems.the most temperature is 800, the pressure is <=6.4Mpa,the leakiness rate is 1x10-3cm3/S. If both of sides be adhered flexible graphite, the leakiness rate is 1x10-5cm3/SBy their sealing efficiently, provide outstanding resilience, while the metal jacket guarantees excellent sealing and protects the filler against pressure conditions, fluctuating temperatures and corrosion.
