Q-365 FLUOROELASTOMER 75 Q RING

QV70365 is an AS568-365 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 6.975 in (177.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.395 in (187.83 mm). In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. It resists petroleum oils and fuels, aromatic hydrocarbons, and chlorinated solvents. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or amines are present. The profile itself contributes a parting line located away from the sealing surface and resistance to the spiral twisting that defeats round-section rings.

Common environments for this compound include automotive fuel systems, chemical processing, and semiconductor equipment.

QV70365 ships individually. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
