6MM CS X 53MM ID BLACK BUNA 70D

H6X53 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 53 mm (2.087 in), a cross section of 6 mm (0.236 in), and an outside diameter of 65 mm (2.56 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. It resists hydraulic fluids, many alcohols, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).

Maintenance and OEM teams specify it across construction equipment, fluid power, and automotive.

H6X53 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
