2MM CS X 125MM ID BLACK BUNA 70D

The H2X125 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 125 mm (4.921 in), a cross section of 2 mm (0.079 in), and an outside diameter of 129 mm (5.08 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Expect good resistance to greases and lubricants, petroleum-based oils, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong acids or ketones.

It sees regular use in automotive, agricultural equipment, and fluid power.
