3MM CS X 85MM ID BLACK BUNA 70D

APG stocks the H3X85, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 85 mm (3.346 in), a cross section of 3 mm (0.118 in), and an outside diameter of 91 mm (3.58 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is valued for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Expect good resistance to greases and lubricants, water, and hydraulic fluids. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in strong acids or automotive brake fluid.

Common environments for this compound include fluid power, general industrial maintenance, and automotive.

H3X85 ships individually. Unit weight is approximately 2.43 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
