Q-034 FLUOROELASTOMER 75 Q RING

Ordered as QV70034, this is an AS568-034 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 2.114 in (53.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.254 in (57.25 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Expect good resistance to petroleum oils and fuels, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or hot water and steam.

Typical settings include high-temperature process equipment, semiconductor equipment, and chemical processing.

Reference part number QV70034 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 1/8 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.
