-450 BLACK BUNA 90D O-RING

Part number H90450 is an AS568-450 black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 10.475 in (266.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 11.025 in (280.04 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is specified here for low compression set under sustained load, strong abrasion and tear resistance. It resists petroleum-based oils, many alcohols, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.

Typical settings include fluid power, automotive, and general industrial maintenance.
