3MM CS X 82MM ID BLACK BUNA 90D

The H90M3X82 is a black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 82 mm (3.228 in), a cross section of 3 mm (0.118 in), and an outside diameter of 88 mm (3.46 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to hydraulic fluids, propane and butane, and water. Buna-N (Nitrile) is known for low compression set under sustained load, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to strong acids or automotive brake fluid will shorten service life.

Maintenance and OEM teams specify it across hydraulic and pneumatic systems, fluid power, and general industrial maintenance.

This item is sold individually under part number H90M3X82. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
