5.7MM CS X 69.2MM ID BLACK BUNA 90D

H90M5.7X69.2 is a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 69.2 mm (2.724 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 80.6 mm (3.17 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists petroleum-based oils, propane and butane, and hydraulic fluids. Buna-N (Nitrile) is known for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving strong acids or automotive brake fluid call for a different compound.

Common environments for this compound include automotive, construction equipment, and hydraulic and pneumatic systems.

H90M5.7X69.2 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
