2.5MM CS X 34MM ID BLACK BUNA 70D

Ordered as H2.5X34, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 34 mm (1.339 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 39 mm (1.54 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists greases and lubricants, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).

You will find this material specified across agricultural equipment, hydraulic and pneumatic systems, and construction equipment.
