Q-136 BUNA 70 Q RING

APG stocks the QH70136, an AS568-136 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring measuring an inside diameter of 1.987 in (50.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.193 in (55.7 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against water, many alcohols, and petroleum-based oils. Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.

Common environments for this compound include hydraulic and pneumatic systems, fluid power, and agricultural equipment.

Order part number QH70136, sold individually. Unit weight is approximately 1.0651 g and nominal inside diameter is listed as 2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
