568-374 BUNA 70 SQUARE CUT RINGS

Part number SH70374 is an AS568-374 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring measuring an inside diameter of 9.225 in (234.32 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.645 in (244.98 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The compound resists petroleum-based oils, many alcohols, and hydraulic fluids. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving strong acids or automotive brake fluid call for a different compound.

Common environments for this compound include construction equipment, hydraulic and pneumatic systems, and fluid power.
