High-Temperature Oil-Resistant Carbon/Buna-N Pipe Gaskets

These blended carbon/Buna-N rubber gaskets are unaffected by oil and temperatures up to 650° F. 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.

High-Temperature Oil-Resistant Carbon/Buna-N Pipe Gaskets with Bolt Holes

Carbon is blended with Buna-N rubber for gaskets that are unaffected by oil and temperatures up to 650° F. 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.
