Ordered as SH70225, this is an AS568-225 black Buna-N (Nitrile) 70 Shore A Square-Cut Ring supplied with an inside diameter of 1.859 in (47.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.137 in (54.28 mm). The 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 reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The compound resists hydraulic fluids, water, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). The profile itself contributes a rectangular section that will not roll in the groove 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.
Typical settings include construction equipment, general industrial maintenance, and fluid power.
Stocked as SH70225 and sold individually. Unit weight is approximately 2.292 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
