This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A with an inside diameter of 265 mm (10.433 in), a cross section of 5.3 mm (0.209 in), and an outside diameter of 275.6 mm (10.85 in), catalogued under part number H5.3X265. 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 low compression set under sustained load, reliable performance in both static and dynamic service. Expect good resistance to greases and lubricants, hydraulic fluids, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.

It sees regular use in fluid power, construction equipment, and general industrial maintenance.
