568-924 BUNA 70 SQUARE CUT RINGS

This quad-ring is supplied in AS568-924 black Buna-N (Nitrile) 70 Shore A square profile measuring an inside diameter of 1.72 in (43.69 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 1.956 in (49.68 mm), catalogued under part number SH70924. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against many alcohols, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).

It sees regular use in fluid power, hydraulic and pneumatic systems, and agricultural equipment.

Reference part number SH70924 when ordering; the item is sold individually. Nominal inside diameter is listed as 1 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
