Q-260 BUNA 70 Q RING

The QH70260 is an AS568-260 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring with an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against many alcohols, hydraulic fluids, and water. That behavior comes from the compound itself: Buna-N (Nitrile) offers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in automotive brake fluid or polar solvents.

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

Order part number QH70260, sold individually. Unit weight is approximately 6.2983 g and nominal inside diameter is listed as 6 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
