2.5MM CS X 50MM ID BLACK BUNA 70D

The H2.5X50 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 50 mm (1.969 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 55 mm (2.17 in). This 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 automotive brake fluid or polar solvents are present.

Typical settings include hydraulic and pneumatic systems, construction equipment, and fluid power.
