-033 BLACK BUNA 90D O-RING

This o-ring is supplied in AS568-033 black Buna-N (Nitrile) 90 Shore A built to an inside diameter of 1.989 in (50.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.129 in (54.08 mm), catalogued under part number H90033. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, low compression set under sustained load. Expect good resistance to greases and lubricants, hydraulic fluids, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.

You will find this material specified across automotive, general industrial maintenance, and hydraulic and pneumatic systems.

Stocked as H90033 and sold individually. Unit weight is approximately 0.5526 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
