5MM CS X 95MM ID BLACK BUNA 70D

Part number H5X95 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 95 mm (3.74 in), a cross section of 5 mm (0.197 in), and an outside diameter of 105 mm (4.13 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists propane and butane, hydraulic fluids, and greases and lubricants. 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). Applications involving ozone and direct sunlight or polar solvents call for a different compound.

Typical settings include construction equipment, automotive, and hydraulic and pneumatic systems.

Order part number H5X95, sold individually. Unit weight is approximately 7.425 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
