-465 BLACK BUNA 90D O-RING

H90465 is an AS568-465 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 17.955 in (456.06 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.505 in (470.03 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. The material holds up against many alcohols, petroleum-based oils, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or automotive brake fluid will shorten service life.

Common environments for this compound include construction equipment, general industrial maintenance, and fluid power.
