-324 BLACK BUNA 90D O-RING

Part number H90324 is an AS568-324 black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 1.35 in (34.29 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.77 in (44.96 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to hydraulic fluids, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where automotive brake fluid or polar solvents are present.

You will find this material specified across general industrial maintenance, fluid power, and agricultural equipment.

This item is sold individually under part number H90324. Unit weight is approximately 3.667 g. Review your operating media and conditions against this specification before installation.
