APG stocks the VQ4159, an AS568-159 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 4.987 in (126.67 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.193 in (131.9 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

As a material, Viton® (FKM) offers long service life in hot, chemically aggressive environments and outstanding high-temperature capability. It resists many acids, aromatic hydrocarbons, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

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

This item is sold individually under part number VQ4159. As always, verify media compatibility and operating conditions against the requirements of your specific application.
