    Ultra-Chemical-Resistant High-Strength PTFE Pipe Gaskets

    Image of ProductInUse. Front orientation. Pipe Gaskets. Ultra-Chemical-Resistant High-Strength PTFE Pipe Gaskets.
    Reinforced with fiberglass filler for strength, these PTFE gaskets won’t thin out when compressed. They resist hydrocarbons, solvents, refrigerants, and moderate concentrations of acids. Also known as ring gaskets, use them with raised-surface pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. All gaskets are compatible with low-pressure pipe flanges and are sized to meet ANSI standards.

    Ultra-Chemical-Resistant High-Strength PTFE Pipe Gaskets with Bolt Holes

    Image of ProductInUse. Front orientation. Pipe Gaskets. Ultra-Chemical-Resistant High-Strength PTFE Pipe Gaskets with Bolt Holes.
    A fiberglass filler in these PTFE gaskets provides strength to prevent them from thinning out when compressed. They resist hydrocarbons, solvents, refrigerants, and moderate concentrations of acids. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. All gasket specifications are sized to meet ANSI standards.
    Plain-Back Gaskets for ANSI Flanges
    For ANSI Class 150—Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges.
    For ANSI Class 300—Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

    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.

    Profile

    Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston seals. They have two high-strength backup rings that protect against extrusion.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
