-362 BLACK BUNA 70D O-RING

H70362 is an AS568-362 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 6.225 in (158.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.645 in (168.78 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against petroleum-based oils, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or polar solvents.

It sees regular use in fluid power, general industrial maintenance, and agricultural equipment.
