3MM CS X 76MM ID BLACK BUNA 90D

This o-ring is supplied in black Buna-N (Nitrile) 90 Shore A measuring an inside diameter of 76 mm (2.992 in), a cross section of 3 mm (0.118 in), and an outside diameter of 82 mm (3.23 in), catalogued under part number H90M3X76. It remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists hydraulic fluids, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or ozone and direct sunlight are present.

Common environments for this compound include fluid power, construction equipment, and agricultural equipment.
