5MM CS X 26MM ID BLACK BUNA 70D

H5X26 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 26 mm (1.024 in), a cross section of 5 mm (0.197 in), and an outside diameter of 36 mm (1.42 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. The compound resists water, hydraulic fluids, and petroleum-based oils. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or ozone and direct sunlight call for a different compound.

Maintenance and OEM teams specify it across hydraulic and pneumatic systems, fluid power, and construction equipment.
