568-463 BUNA 70 SQUARE CUT RINGS

Part number SH70463 is an AS568-463 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 16.955 in (430.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.505 in (444.63 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

It resists water, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving polar solvents or strong acids call for a different compound.

Typical settings include automotive, agricultural equipment, and hydraulic and pneumatic systems.

Stocked as SH70463 and sold individually. Nominal inside diameter is listed as 17 inch. Check the compound against your process media, pressure and temperature before committing to a design.
