568-901 BUNA 70 SQUARE CUT RINGS

This quad-ring is supplied in AS568-901 black Buna-N (Nitrile) 70 Shore A square profile with an inside diameter of 0.185 in (4.7 mm), a cross section of 0.056 in (1.42 mm), and an outside diameter of 0.297 in (7.54 mm), catalogued under part number SH70901. It uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

It resists many alcohols, propane and butane, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).

Common environments for this compound include agricultural equipment, fluid power, and construction equipment.

SH70901 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
