The H50207 is an AS568-207 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 0.546 in (13.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.824 in (20.93 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, most widely specified general-purpose sealing elastomer. It resists petroleum-based oils, hydraulic fluids, 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 ozone and direct sunlight will shorten service life.
Common environments for this compound include automotive, fluid power, and hydraulic and pneumatic systems.
Order part number H50207, sold individually. Nominal inside diameter is listed as 9/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
