-152 BLACK BUNA 90D O-RING

Ordered as H90152, this is an AS568-152 black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 3.237 in (82.22 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.443 in (87.45 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to petroleum-based oils, greases and lubricants, and water. That behavior comes from the compound itself: Buna-N (Nitrile) offers reliable performance in both static and dynamic service, strong abrasion and tear resistance. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where polar solvents or automotive brake fluid are present.

Typical settings include hydraulic and pneumatic systems, general industrial maintenance, and construction equipment.

H90152 ships individually. Unit weight is approximately 2.021 g and nominal inside diameter is listed as 3 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
