Q-177 FLUOROELASTOMER 75 Q RING

QV70177 is an AS568-177 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 9.487 in (240.97 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.693 in (246.2 mm). In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. It resists petroleum oils and fuels, chlorinated solvents, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or ketones and esters call for a different compound. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

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

QV70177 ships individually. Nominal inside diameter is listed as 9 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
