568-119 BUNA 70 SQUARE CUT RINGS

Ordered as SH70119, this is an AS568-119 black Buna-N (Nitrile) 70 Shore A Square-Cut Ring with an inside diameter of 0.924 in (23.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.13 in (28.7 mm). The square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. This material stands up to water, petroleum-based oils, and propane and butane. Published continuous service range is -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 greater resistance to extrusion than a round section of the same size and simple lathe-cut manufacture at low tooling cost. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.

It sees regular use in general industrial maintenance, hydraulic and pneumatic systems, and fluid power.
