4MM CS X 82MM ID BLACK BUNA 90D

H90M4X82 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 4 mm (0.157 in), and an outside diameter of 90 mm (3.54 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. It resists greases and lubricants, propane and butane, and many alcohols. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where automotive brake fluid or polar solvents are present.

You will find this material specified across fluid power, hydraulic and pneumatic systems, and construction equipment.

H90M4X82 ships individually. Unit weight is approximately 4.384 g. Check the compound against your process media, pressure and temperature before committing to a design.
