568-036 BUNA 70 SQUARE CUT RINGS

Ordered as SH70036, this is an AS568-036 black Buna-N (Nitrile) 70 Shore A Square-Cut Ring built to an inside diameter of 2.364 in (60.05 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.504 in (63.6 mm). The square-cut ring offers greater contact area against the gland wall than an equivalent o-ring.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. The material holds up against greases and lubricants, many alcohols, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or ozone and direct sunlight are present. The profile itself contributes a rectangular section that will not roll in the groove and greater resistance to extrusion than a round section of the same size. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.

Typical settings include construction equipment, automotive, and agricultural equipment.
