568-244 BUNA 70 SQUARE CUT RINGS

Part number SH70244 is an AS568-244 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 4.234 in (107.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.512 in (114.6 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Buna-N (Nitrile) offers low compression set under sustained load, reliable performance in both static and dynamic service. Expect good resistance to hydraulic fluids, water, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving ketones or polar solvents call for a different compound.

Typical settings include general industrial maintenance, fluid power, and hydraulic and pneumatic systems.
