4.5MM CS X 95MM ID BLACK BUNA 70D

APG stocks the H4.5X95, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 95 mm (3.74 in), a cross section of 4.5 mm (0.177 in), and an outside diameter of 104 mm (4.09 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against many alcohols, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.

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