5MM CS X 90MM ID BLACK BUNA 90D

Ordered as H90M5X90, this is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 90 mm (3.543 in), a cross section of 5 mm (0.197 in), and an outside diameter of 100 mm (3.94 in). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to hydraulic fluids, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) offers reliable performance in both static and dynamic service, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where automotive brake fluid or ketones are present.

You will find this material specified across automotive, fluid power, and hydraulic and pneumatic systems.
