-150 BLACK BUNA 70D O-RING

Ordered as H70150, this is an AS568-150 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 2.862 in (72.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.068 in (77.93 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists petroleum-based oils, 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. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or ketones are present.

You will find this material specified across automotive, construction equipment, and fluid power.

H70150 ships individually. Unit weight is approximately 1.5578 g. Review your operating media and conditions against this specification before installation.
