This o-ring is supplied in AS568-452 black Buna-N (Nitrile) 50 Shore A measuring an inside diameter of 11.475 in (291.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 12.025 in (305.44 mm), catalogued under part number H50452. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
It resists greases and lubricants, many alcohols, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).
Maintenance and OEM teams specify it across fluid power, construction equipment, and general industrial maintenance.
H50452 ships individually. Nominal inside diameter is listed as 11 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
