The H50413 is an AS568-413 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 2.975 in (75.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.525 in (89.54 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The material holds up against many alcohols, petroleum-based oils, and hydraulic fluids. Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or automotive brake fluid call for a different compound.
Maintenance and OEM teams specify it across fluid power, general industrial maintenance, and hydraulic and pneumatic systems.
H50413 ships individually. Review your operating media and conditions against this specification before installation.
