3MM CS X 215MM ID BLACK BUNA 70D

Part number H3X215 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 215 mm (8.465 in), a cross section of 3 mm (0.118 in), and an outside diameter of 221 mm (8.7 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against many alcohols, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 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, agricultural equipment, and hydraulic and pneumatic systems.
