568-122 BUNA 70 SQUARE CUT RINGS

Part number SH70122 is an AS568-122 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 1.112 in (28.24 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.318 in (33.48 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

As a material, Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. The material holds up against petroleum-based oils, propane and butane, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where polar solvents or ketones are present.

You will find this material specified across agricultural equipment, automotive, and construction equipment.
