7MM CS X 412MM ID BLACK BUNA 70D

The H7X412 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 412 mm (16.22 in), a cross section of 7 mm (0.276 in), and an outside diameter of 426 mm (16.77 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against petroleum-based oils, many alcohols, and water. Buna-N (Nitrile) is known for low compression set under sustained load, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or polar solvents will shorten service life.

Common environments for this compound include automotive, agricultural equipment, and fluid power.
