Q-354 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-354 black Viton® (FKM) 75 Shore A quad profile supplied with an inside diameter of 5.1 in (129.54 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.52 in (140.21 mm), catalogued under part number QV70354. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. The compound resists petroleum oils and fuels, chlorinated solvents, and many acids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

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

Order part number QV70354, sold individually. Unit weight is approximately 19.288 g and nominal inside diameter is listed as 5 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
