3MM CS X 183.5MM ID BLACK BUNA 70D

Part number H3X183.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 183.5 mm (7.224 in), a cross section of 3 mm (0.118 in), and an outside diameter of 189.5 mm (7.46 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is known for low compression set under sustained load and an economical choice for high-volume maintenance programs. The compound resists propane and butane, hydraulic fluids, and water. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to polar solvents or strong acids will shorten service life.

Typical settings include general industrial maintenance, automotive, and agricultural equipment.
