-213 BLACK BUNA 90D O-RING

Part number H90213 is an AS568-213 black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 0.921 in (23.39 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.199 in (30.45 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists propane and butane, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and 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). Applications involving polar solvents or automotive brake fluid call for a different compound.

It sees regular use in construction equipment, fluid power, and hydraulic and pneumatic systems.
