*Q-454 FLUOROELASTOMER 75 Q RING

Ordered as QV70454, this is an AS568-454 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 12.475 in (316.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 13.025 in (330.84 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is known for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. This material stands up to many acids, petroleum oils and fuels, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or ketones and esters will shorten service life. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

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