-122 BLACK BUNA 90D O-RING

The H90122 is an AS568-122 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 1.112 in (28.24 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.318 in (33.48 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists petroleum-based oils, hydraulic fluids, and water. Buna-N (Nitrile) delivers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with polar solvents or automotive brake fluid.

It sees regular use in automotive, fluid power, and general industrial maintenance.

Stocked as H90122 and sold individually. Unit weight is approximately 0.7064 g and nominal inside diameter is listed as 1 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
