568-144 BUNA 70 SQUARE CUT RINGS

APG stocks the SH70144, an AS568-144 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 2.487 in (63.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.693 in (68.4 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

It resists water, propane and butane, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or polar solvents.

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

This item is sold individually under part number SH70144. Unit weight is approximately 1.364 g. Review your operating media and conditions against this specification before installation.
