Buna 70-2mmCSx8mmID-Black-Pk100

The SB-H2X8-100 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 8 mm (0.315 in), a cross section of 2 mm (0.079 in), and an outside diameter of 12 mm (0.47 in). This o-ring compresses into its gland to block fluid or gas migration across a joint. Supplementary detail from the product record: 8MMIDX2MMCS.

Expect good resistance to water, greases and lubricants, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with polar solvents or ketones.

It sees regular use in general industrial maintenance, construction equipment, and agricultural equipment.

SB-H2X8-100 ships by the bag. 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.
