This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 9.5 mm (0.374 in), a cross section of 3 mm (0.118 in), and an outside diameter of 15.5 mm (0.61 in), catalogued under part number H3X9.5. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The compound resists petroleum-based oils, greases and lubricants, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or ozone and direct sunlight call for a different compound.
You will find this material specified across fluid power, general industrial maintenance, and hydraulic and pneumatic systems.
Stocked as H3X9.5 and sold individually. Unit weight is approximately 0.3467 g. Check the compound against your process media, pressure and temperature before committing to a design.
