568-471 BUNA 70 SQUARE CUT RINGS

This quad-ring is supplied in AS568-471 black Buna-N (Nitrile) 70 Shore A square profile with an inside diameter of 21.955 in (557.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 22.505 in (571.63 mm), catalogued under part number SH70471. It uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The material holds up against water, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where strong acids or ketones are present.

Common environments for this compound include fluid power, agricultural equipment, and construction equipment.

SH70471 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
