    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.

    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. 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. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.
