7MM CS X 630MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 630 mm (24.803 in), a cross section of 7 mm (0.276 in), and an outside diameter of 644 mm (25.35 in), catalogued under part number H7X630. It remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Expect good resistance to hydraulic fluids, propane and butane, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or strong acids will shorten service life.

Maintenance and OEM teams specify it across general industrial maintenance, automotive, and hydraulic and pneumatic systems.
