    Ultra-High-Temperature Vermiculite Pipe Gaskets with Bolt Holes

    Image of ProductInUse. Front orientation. Pipe Gaskets. Ultra-High-Temperature Vermiculite Pipe Gaskets with Bolt Holes.
    Our highest temperature gaskets, these are made of vermiculite to withstand temperatures up to 1800° F. They are reinforced with a stainless steel insert for added strength under pressures up to 740 psi. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.

    Ultra-High-Temperature Chemical-Resistant Vermiculite Gasket Material

    In addition to handling temperatures up to 1800° F, these vermiculite gasket sheets resist acids (except hydrofluoric), alkalies, and detergents. They have a stainless steel insert that provides strength under pressure. Use them when a strong seal is required in boilers and furnaces. Cut with a flush cutter, water jet, or laser cutter.

    Profile

    PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
