568-475 BUNA 70 SQUARE CUT RINGS

The SH70475 is an AS568-475 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 25.94 in (658.88 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 26.49 in (672.85 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Buna-N (Nitrile) offers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. The compound resists petroleum-based oils, hydraulic fluids, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in ketones or strong acids.

You will find this material specified across automotive, fluid power, and construction equipment.

SH70475 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
