-323 BLACK BUNA 90D O-RING

H90323 is an AS568-323 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 1.287 in (32.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.707 in (43.36 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. It resists greases and lubricants, petroleum-based oils, and water. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ozone and direct sunlight will shorten service life.

It sees regular use in agricultural equipment, fluid power, and automotive.

H90323 ships individually. Unit weight is approximately 3.6016 g. Review your operating media and conditions against this specification before installation.
