Oil-Resistant Compressible Buna-N Pipe Gaskets
These compressible Buna-N rubber gaskets ensure a tight seal. They resist oil, water, and salts. 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 gasket specifications are sized to 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 Buna-N Gaskets for Grooved-End Pipe Fittings
Create a tight seal on grooved-end pipe fittings that are exposed to oil. These gaskets are Buna-N, so they won't break down from oil.

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. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges. Adhesive-back gaskets stay in place to make installation easier.
Gaskets for DIN flange sizes are sized to fit pressure class PN16 flanges.

Oil-Resistant Compressible Buna-N Pipe
Gaskets with Bolt Holes for Dissimilar Metals
The included plastic sleeves and washers provide a layer of protection against dielectric corrosion, which occurs when different metals are joined. Commonly called full-face gaskets, these cover the entire face of flat-surface pipe flanges and align with the bolt holes. They’re made of compressible Buna-N rubber to ensure a tight seal. They resist oil, water, and salts. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards. Each gasket comes with one full-length sleeve for each bolt hole, plus two phenolic and two zinc-plated metal washers for each bolt hole. Bolts are not included.
