Buna 70-332-Black-Pk50

The SB-H70332-50 is an AS568-332 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 2.35 in (59.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.77 in (70.36 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Supplementary detail from the product record: 2.75IDX2.375"ODX.1875"CS.

Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. This material stands up to petroleum-based oils, many alcohols, and water. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or polar solvents are present.

Common environments for this compound include agricultural equipment, hydraulic and pneumatic systems, and automotive.

SB-H70332-50 ships by the bag. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
