-001 BLACK BUNA 70D O-RING

H70001 is an AS568-001 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.029 in (0.74 mm), a cross section of 0.04 in (1.02 mm), and an outside diameter of 0.109 in (2.77 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists many alcohols, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) offers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).

Common environments for this compound include construction equipment, hydraulic and pneumatic systems, and agricultural equipment.
