Q-359 FLUOROELASTOMER 75 Q RING

QV70359 is an AS568-359 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 5.725 in (145.42 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.145 in (156.08 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The compound resists aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. Viton® (FKM) delivers outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with low-molecular-weight organic acids or ketones and esters. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

Common environments for this compound include high-temperature process equipment, chemical processing, and semiconductor equipment.

This item is sold individually under part number QV70359. Unit weight is approximately 21.696 g and nominal inside diameter is listed as 5 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
