4384-514AD MINNESOTA RUBBER QUAD RING

Part number VQ4384 is an AS568-384 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 14.975 in (380.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 15.395 in (391.03 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and industry benchmark where nitrile reaches its thermal limit. The compound resists engine and transmission fluids, aromatic hydrocarbons, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with amines or low-molecular-weight organic acids.

It sees regular use in high-temperature process equipment, chemical processing, and aerospace.

This item is sold individually under part number VQ4384. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
