*4144-514AD MINNESOTA RUBBER QUAD RING

APG stocks the VQ4144, an AS568-144 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 2.487 in (63.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.693 in (68.4 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Expect good resistance to chlorinated solvents, petroleum oils and fuels, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or ketones and esters will shorten service life.

Common environments for this compound include chemical processing, automotive fuel systems, and oil and gas.

Order part number VQ4144, sold individually. Nominal inside diameter is listed as 2 1/2. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
