1.2MM CS X 2.5MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 2.5 mm (0.098 in), a cross section of 1.2 mm (0.047 in), and an outside diameter of 4.9 mm (0.19 in), catalogued under part number H1.2X2.5. It creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against propane and butane, greases and lubricants, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with ketones or polar solvents.

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

Stocked as H1.2X2.5 and sold individually. Review your operating media and conditions against this specification before installation.
