Part number H50330 is an AS568-330 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is widely chosen for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. The compound resists petroleum-based oils, hydraulic fluids, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving automotive brake fluid or strong acids call for a different compound.
