5MM CS X 61MM ID BLACK BUNA 70D

Ordered as H5X61, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 61 mm (2.402 in), a cross section of 5 mm (0.197 in), and an outside diameter of 71 mm (2.8 in). The 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 low compression set under sustained load. Expect good resistance to petroleum-based oils, hydraulic fluids, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or automotive brake fluid will shorten service life.

You will find this material specified across hydraulic and pneumatic systems, construction equipment, and fluid power.
