3.53MM CS X 52.39MM ID BLACK BUNA 70D

The H3.53X52.39 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 52.39 mm (2.063 in), a cross section of 3.53 mm (0.139 in), and an outside diameter of 59.45 mm (2.34 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. It resists propane and butane, many alcohols, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or ozone and direct sunlight will shorten service life.

You will find this material specified across construction equipment, general industrial maintenance, and hydraulic and pneumatic systems.
