-112 BLACK BUNA 50D O-RING

H50112 is an AS568-112 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 0.487 in (12.37 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.693 in (17.6 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to petroleum-based oils, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong acids or automotive brake fluid.

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