568-334 BUNA 70 SQUARE CUT RINGS

Part number SH70334 is an AS568-334 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 2.6 in (66.04 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.02 in (76.71 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is specified here for low compression set under sustained load, strong abrasion and tear resistance. The compound resists propane and butane, petroleum-based oils, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or strong acids call for a different compound.

Maintenance and OEM teams specify it across general industrial maintenance, construction equipment, and agricultural equipment.

Reference part number SH70334 when ordering; the item is sold individually. Unit weight is approximately 7.3219 g and nominal inside diameter is listed as 2 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
