-447 BLACK BUNA 70D O-RING

H70447 is an AS568-447 black Buna-N (Nitrile) 70 Shore A O-Ring with 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). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is known for strong abrasion and tear resistance, low compression set under sustained load. The material holds up against many alcohols, hydraulic fluids, and petroleum-based oils. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or polar solvents call for a different compound.

Common environments for this compound include construction equipment, hydraulic and pneumatic systems, and general industrial maintenance.
