SH70333 is an AS568-333 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring measuring an inside diameter of 2.475 in (62.87 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.895 in (73.53 mm). In service, this quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. The compound resists propane and butane, petroleum-based oils, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to automotive brake fluid or ketones will shorten service life.

You will find this material specified across agricultural equipment, hydraulic and pneumatic systems, and general industrial maintenance.
