Q-475 FLUOROELASTOMER 75 Q RING

QV70475 is an AS568-475 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 25.94 in (658.88 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 26.49 in (672.85 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified here for outstanding high-temperature capability, excellent resistance to compression set and permeation. This material stands up to chlorinated solvents, aggressive chemicals, and aromatic hydrocarbons. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with amines or ketones and esters.

Maintenance and OEM teams specify it across oil and gas, high-temperature process equipment, and aerospace.
