SB-H70036-10 is an AS568-036 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 2.364 in (60.05 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.504 in (63.6 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint. Source specification: 0.070CSX2.364"IDX2.504"OD.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs and low compression set under sustained load. The compound resists many alcohols, water, and hydraulic fluids. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with polar solvents or strong acids.

Maintenance and OEM teams specify it across construction equipment, hydraulic and pneumatic systems, and fluid power.
