568-164 BUNA 70 SQUARE CUT RINGS

SH70164 is an AS568-164 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 6.237 in (158.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.443 in (163.65 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. It resists propane and butane, hydraulic fluids, and water. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.

Common environments for this compound include fluid power, general industrial maintenance, and agricultural equipment.
