3.5MM CS X 60MM ID BLACK BUNA 70D

H3.5X60 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 60 mm (2.362 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 67 mm (2.64 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to greases and lubricants, petroleum-based oils, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) offers low compression set under sustained load and an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or ketones are present.

Common environments for this compound include general industrial maintenance, automotive, and hydraulic and pneumatic systems.
