    High-Temperature Graphite Pipe Gaskets

    Image of ProductInUse. Front orientation. Pipe Gaskets. High-Temperature Graphite Pipe Gaskets.
    Able to withstand temperatures up to 750° F, these graphite gaskets have a stainless steel insert for strength to handle pressure up to 1,000 psi. 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 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.
    For ANSI Class 600—Gaskets for ANSI Class 600 flanges are compatible with high-pressure pipe flanges.
    For ANSI Class 1500—Gaskets for ANSI Class 1500 flanges are compatible with extreme-pressure pipe flanges.

    Image of ProductInUse. Front orientation. Pipe Gaskets. High-Temperature Graphite Pipe Gaskets with Bolt Holes.
    Able to withstand temperatures up to 750° F, these graphite gaskets have a stainless steel insert for strength to handle pressure up to 1,000 psi. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. All gaskets are sized to meet ANSI standards.
