2.5MM CS X 17MM ID BLACK BUNA 70D

APG stocks the H2.5X17, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 17 mm (0.669 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 22 mm (0.87 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to greases and lubricants, propane and butane, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is valued 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. It should not be specified for service in strong acids or polar solvents.

Typical settings include fluid power, general industrial maintenance, and automotive.

Reference part number H2.5X17 when ordering; the item is sold individually. Unit weight is approximately 0.3877 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
