2.5MM CS X 124MM ID BLACK BUNA 70D

H2.5X124 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 124 mm (4.882 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 129 mm (5.08 in). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against water, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or strong acids will shorten service life.

It sees regular use in automotive, agricultural equipment, and hydraulic and pneumatic systems.
