Q-208 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-208 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 0.609 in (15.47 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.887 in (22.53 mm), catalogued under part number QV70208. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to many acids, aggressive chemicals, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

Maintenance and OEM teams specify it across high-temperature process equipment, automotive fuel systems, and aerospace.

Order part number QV70208, sold individually. Unit weight is approximately 1.1971 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
