Q-047 FLUOROELASTOMER 75 Q RING

QV70047 is an AS568-047 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 4.489 in (114.02 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.629 in (117.58 mm). In service, this quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Expect good resistance to petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with amines or ketones and esters.

Maintenance and OEM teams specify it across aerospace, chemical processing, and semiconductor equipment.

QV70047 ships individually. Nominal inside diameter is listed as 4 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
