Q-220 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-220 black Viton® (FKM) 75 Shore A measuring an inside diameter of 1.359 in (34.52 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.637 in (41.58 mm), catalogued under part number QV70220. It uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is specified for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. The compound resists chlorinated solvents, engine and transmission fluids, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Maintenance and OEM teams specify it across automotive fuel systems, chemical processing, and semiconductor equipment.

Reference part number QV70220 when ordering; the item is sold individually. Unit weight is approximately 2.385 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
