Product Specification

-
This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 75 mm (2.953 in), a cross section of 7 mm (0.276 in), and an outside diameter of 89 mm (3.5 in), catalogued under part number H7X75. It remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. It resists greases and lubricants, propane and butane, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.

It sees regular use in automotive, hydraulic and pneumatic systems, and fluid power.

Reference part number H7X75 when ordering; the item is sold individually. Unit weight is approximately 12.108 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
