VCFS™ Isolating Gaskets/Kits
The VCFS™* adds fire service capability to the standard Pikotek® 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. Due to the fact that every fire is unique and many uncontrolled variables are present, no other claims regarding suitability or performance in a fire are made. Each designer, user and/or operator will need to assess their individual situation when deciding to install FS style gaskets. Covered under patents 266755, 7976074, 2271866.
