H2.5X148 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 148 mm (5.827 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 153 mm (6.02 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Buna-N (Nitrile) offers low compression set under sustained load, strong abrasion and tear resistance. Expect good resistance to propane and butane, water, and hydraulic fluids. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to polar solvents or automotive brake fluid will shorten service life.
You will find this material specified across hydraulic and pneumatic systems, fluid power, and agricultural equipment.
