DEFENDER FS™ Sealing/Isolation Gaskets (Fire Safe)

DEFENDER™ fire safe isolation kits are the ultimate in corrosion protection, seal security and fire protection all in one. The Kammprofile core and Matrix PTFE primary seal ensures seal integrity at the highest pressures while the special PTFE coating and GRE complete the flange isolation. In the event of a fire special washers and a secondary seal prevent the flange from failing. Tested and accredited to API 6FB “fire safe”


sleeve and washerSleeve and Washer Sets

Lamons sleeve and washers sets, when combined with our sealing/isolation gaskets, complete a Flange Isolation Kit. For a successful flange isolation kit, it’s critical to use the appropriate material for your application. Compressive strength, flexural strength, and cut through resistance are key material physical properties that should not be over looked.
