Product Specification

-
Part number H10X270 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 270 mm (10.63 in), a cross section of 10 mm (0.394 in), and an outside diameter of 290 mm (11.42 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Expect good resistance to hydraulic fluids, petroleum-based oils, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or automotive brake fluid call for a different compound.

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