-176 BLACK BUNA 70D O-RING

This o-ring is supplied in AS568-176 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 9.237 in (234.62 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.443 in (239.85 mm), catalogued under part number H70MD176. It creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, reliable performance in both static and dynamic service. The compound resists greases and lubricants, water, and hydraulic fluids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or polar solvents will shorten service life.

This item is metal detectable for HACCP and foreign-body control programs. It sees regular use in fluid power, hydraulic and pneumatic systems, and construction equipment.

Reference part number H70MD176 when ordering; the item is sold individually. Nominal inside diameter is listed as 9 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
