APG stocks the H50211, an AS568-211 black Buna-N (Nitrile) 50 Shore A O-Ring with an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Buna-N (Nitrile) is valued for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Expect good resistance to petroleum-based oils, water, and many alcohols. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or automotive brake fluid will shorten service life.
Common environments for this compound include general industrial maintenance, construction equipment, and agricultural equipment.
This item is sold individually under part number H50211. Unit weight is approximately 0.001 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
