2.5MM CS X 240MM ID BLACK BUNA 70D

APG stocks the H2.5X240, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 2.5 mm (0.098 in), a cross section of 240 mm (9.45 in), and an outside diameter of 245 mm (9.65 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists many alcohols, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Typical settings include general industrial maintenance, construction equipment, and fluid power.
