-365 BLACK BUNA 70D O-RING

This o-ring is supplied in AS568-365 black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 6.975 in (177.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.395 in (187.83 mm), catalogued under part number H70365. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to water, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or strong acids.

Typical settings include automotive, agricultural equipment, and fluid power.
