Q-169 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-169 black Viton® (FKM) 75 Shore A built to an inside diameter of 7.487 in (190.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.693 in (195.4 mm), catalogued under part number QV70169. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The compound resists petroleum oils and fuels, aggressive chemicals, and many acids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

You will find this material specified across high-temperature process equipment, aerospace, and oil and gas.

This item is sold individually under part number QV70169. Application requirements vary, so validate compatibility with your process conditions prior to installation.
