3MM CS X 114.5MM ID BLACK BUNA 70D

APG stocks the H3X114.5, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 114.5 mm (4.508 in), a cross section of 3 mm (0.118 in), and an outside diameter of 120.5 mm (4.74 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. The material holds up against propane and butane, water, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ketones will shorten service life.

Typical settings include construction equipment, general industrial maintenance, and hydraulic and pneumatic systems.
