A specially formulated, all purpose family of Garlock inorganic asbestos-free fiber gasketing which exceeds the parameters of aramid fiber reinforced gasketing in thermal stability, torque retention, sealability and weight loss. As inorganic fibers do not oxidize IFG and ST-706 provides greater thermal and dimensional stability during process cycling. IFG is produced to meet most service requirements. The IFG material also offers flexibility when writing corporate piping specifications – giving you the right gasket for the right application – the first time. ST-706 is the result of extensive research and development primarily aimed at the requirement for a high temperature gasket, particularly for steam service.
