5.7MM CS X 47.6MM ID BLACK BUNA 70D

Part number H5.7X47.6 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 47.6 mm (1.874 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 59 mm (2.32 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as Metric O-RING, JIS P48A.

The compound resists hydraulic fluids, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or automotive brake fluid are present.

Maintenance and OEM teams specify it across fluid power, hydraulic and pneumatic systems, and general industrial maintenance.
