3.6MM CS X 37.3MM ID BLACK BUNA 70D

Part number H3.6X37.3 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 37.3 mm (1.469 in), a cross section of 3.6 mm (0.142 in), and an outside diameter of 44.5 mm (1.75 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists propane and butane, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with ozone and direct sunlight or ketones.

Common environments for this compound include general industrial maintenance, fluid power, and hydraulic and pneumatic systems.
