Oil-Resistant Aramid/Buna-N Pipe Gaskets

In addition to oil, these blended aramid fiber/Buna-N rubber gaskets resist water and aliphatic hydrocarbons such as ethylene. 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 for ANSI class flanges are sized so all gasket specifications meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges.

Water- and Steam-Resistant EPDM Pipe Gaskets

Resistant to water, steam, and salt water, these gaskets are EPDM rubber. Commonly called 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 for ANSI class flanges are sized so all gasket specifications meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

Oil-Resistant Compressible Buna-N Pipe Gaskets with Bolt Holes

Made of Buna-N rubber, these gaskets compress to ensure a tight seal. They resist oil, water, and salts. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes.

Gaskets for ANSI class flanges are sized so all gasket specifications meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges.
