5MM CS X 125MM ID BLACK BUNA 70D

APG stocks the H5X125, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 125 mm (4.921 in), a cross section of 5 mm (0.197 in), and an outside diameter of 135 mm (5.31 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, low compression set under sustained load. Expect good resistance to hydraulic fluids, greases and lubricants, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving strong acids or automotive brake fluid call for a different compound.

You will find this material specified across agricultural equipment, general industrial maintenance, and fluid power.

H5X125 ships individually. Unit weight is approximately 9.9203 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
