2.62MM CS X 17.86MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A with an inside diameter of 17.86 mm (0.703 in), a cross section of 2.62 mm (0.103 in), and an outside diameter of 23.1 mm (0.91 in), catalogued under part number H2.62X17.86. It remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against hydraulic fluids, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ketones will shorten service life.

Common environments for this compound include automotive, agricultural equipment, and hydraulic and pneumatic systems.

Reference part number H2.62X17.86 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
