4432-514AD MINNESOTA RUBBER QUAD RING

Part number VQ4432 is an AS568-432 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 5.35 in (135.89 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.9 in (149.86 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

It resists many acids, engine and transmission fluids, and aromatic hydrocarbons. Viton® (FKM) is widely chosen for very low compression set at elevated temperature 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. It is not the right choice where ketones and esters or amines are present. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

Maintenance and OEM teams specify it across chemical processing, oil and gas, and automotive fuel systems.

Reference part number VQ4432 when ordering; the item is sold individually. 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.
