568-260 BUNA 70 SQUARE CUT RINGS

APG stocks the SH70260, an AS568-260 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring measuring an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

It resists petroleum-based oils, many alcohols, and water. Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving ozone and direct sunlight or automotive brake fluid call for a different compound.

It sees regular use in hydraulic and pneumatic systems, general industrial maintenance, and fluid power.
