Q-475 FLUOROELASTOMER 75 Q RING

QV70475 is an AS568-475 black Viton® (FKM) 75 Shore A 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. The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

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

Stocked as QV70475 and sold individually. Nominal inside diameter is listed as 26 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
