-447 BLACK BUNA 50D O-RING

The H50447 is an AS568-447 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 8.975 in (227.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 9.525 in (241.94 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against greases and lubricants, petroleum-based oils, and many alcohols. Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ozone and direct sunlight or ketones will shorten service life.

Common environments for this compound include fluid power, construction equipment, and general industrial maintenance.
