2.5MM CS X 38MM ID BLACK BUNA 90D

Part number H90M2.5X38 is a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 38 mm (1.496 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 43 mm (1.69 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. It resists petroleum-based oils, propane and butane, and many alcohols. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where strong acids or automotive brake fluid are present.

Typical settings include fluid power, hydraulic and pneumatic systems, and general industrial maintenance.
