568-916 BUNA 70 SQUARE CUT RINGS

The SH70916 is an AS568-916 black Buna-N (Nitrile) 70 Shore A Square-Cut Ring with an inside diameter of 1.171 in (29.74 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.403 in (35.64 mm). This square-cut ring provides an economical lathe-cut alternative where a moulded o-ring is not required.

As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. It resists propane and butane, water, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with automotive brake fluid or strong acids. The profile itself contributes a flat contact band that spreads sealing load across a wider area 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 hydraulic and pneumatic systems, agricultural equipment, and automotive.
