568-023 BUNA 70 SQUARE CUT RINGS

Ordered as SH70023, this is an AS568-023 black Buna-N (Nitrile) 70 Shore A Square-Cut Ring with an inside diameter of 1.051 in (26.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.191 in (30.25 mm). The square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

It resists petroleum-based oils, propane and butane, and greases and lubricants. Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in automotive brake fluid or ozone and direct sunlight. The profile itself contributes simple lathe-cut manufacture at low tooling cost and a rectangular section that will not roll in the groove. 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, general industrial maintenance, and construction equipment.

This item is sold individually under part number SH70023. Unit weight is approximately 0.3125 g and nominal inside diameter is listed as 1 1/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
