Q-436 FLUOROELASTOMER 75 Q RING

QV70436 is an AS568-436 black Viton® (FKM) 75 Shore A quad profile Quad-Ring supplied with an inside diameter of 5.85 in (148.59 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.4 in (162.56 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

It resists aromatic hydrocarbons, chlorinated solvents, and aggressive chemicals. Viton® (FKM) offers very low compression set at elevated temperature and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.

You will find this material specified across chemical processing, oil and gas, and aerospace.

This item is sold individually under part number QV70436. Nominal inside diameter is listed as 5 7/8 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
