The VQ4434 is an AS568-434 black Viton® (FKM) 75 Shore A quad profile Quad-Ring supplied with an inside diameter of 5.6 in (142.24 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.15 in (156.21 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.
Viton® (FKM) is known for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. The material holds up against aggressive chemicals, many acids, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or amines will shorten service life.
You will find this material specified across semiconductor equipment, aerospace, and oil and gas.
VQ4434 ships individually. 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.
