2.5MM CS X 83MM ID BLACK BUNA 70D

APG stocks the H2.5X83, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 83 mm (3.268 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 88 mm (3.46 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against many alcohols, petroleum-based oils, and water. That behavior comes from the compound itself: Buna-N (Nitrile) offers strong abrasion and tear resistance, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to strong acids or automotive brake fluid will shorten service life.

You will find this material specified across automotive, fluid power, and general industrial maintenance.
