Senja VCFS Insulation Gasket Kit adds fire service capability to the standard VCS design through the use of a secondary sealing element that is capable of maintaining a seal while subject to a 1500°F (815°C) fire. The VCFS fire resistant gasket combines proven sealing performance in aggressive environments with the capability to pass the API 6FB, 3rd Edition fire test³.
Due to its unique pressure activated sealing mechanism, the heat resistant gasket requires far less bolt stress to seal than other gasket types. In addition, the engineered E-ring will serve as a secondary seal during normal operation and the primary sealing element during a fire.
* Note: The “FS” or “Fire Safe” designation denotes only that this gasket has successfully passed the API 6FB fire test.
