-224 BLACK BUNA 90D O-RING

H90224 is an AS568-224 black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 1.734 in (44.04 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.012 in (51.1 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to many alcohols, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for low compression set under sustained load, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to polar solvents or strong acids will shorten service life.

Maintenance and OEM teams specify it across general industrial maintenance, agricultural equipment, and fluid power.
