-162 BLACK BUNA 90D O-RING

APG stocks the H90162, an AS568-162 black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 5.737 in (145.72 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.943 in (150.95 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against propane and butane, petroleum-based oils, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or automotive brake fluid.

It sees regular use in agricultural equipment, fluid power, and hydraulic and pneumatic systems.
