Q-217 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-217 black Viton® (FKM) 75 Shore A measuring an inside diameter of 1.171 in (29.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.449 in (36.8 mm), catalogued under part number QV70217. It uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. This material stands up to many acids, aromatic hydrocarbons, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

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

This item is sold individually under part number QV70217. Unit weight is approximately 2.0431 g. 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.
