This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A with an inside diameter of 69 mm (2.717 in), a cross section of 5.3 mm (0.209 in), and an outside diameter of 79.6 mm (3.13 in), catalogued under part number H5.3X69. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs and low compression set under sustained load. The compound resists petroleum-based oils, hydraulic fluids, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or automotive brake fluid call for a different compound.
Typical settings include hydraulic and pneumatic systems, automotive, and fluid power.
H5.3X69 ships individually. Unit weight is approximately 6.4486 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
