Q-271 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-271 black Viton® (FKM) 75 Shore A measuring an inside diameter of 9.234 in (234.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.512 in (241.6 mm), catalogued under part number QV70271. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Viton® (FKM) is valued for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to 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). Applications involving low-molecular-weight organic acids or amines call for a different compound. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

Common environments for this compound include chemical processing, oil and gas, and aerospace.

Reference part number QV70271 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
