Buna 70-3mmCSx36mmID-Black-Pk25

APG stocks the SB-H3X36-25, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 36 mm (1.417 in), a cross section of 3 mm (0.118 in), and an outside diameter of 42 mm (1.65 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. Source specification: 36MMIDX3MMCS.

Expect good resistance to petroleum-based oils, propane and butane, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. 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.

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

This item is sold by the bag under part number SB-H3X36-25. As always, verify media compatibility and operating conditions against the requirements of your specific application.
