**4273-514AD MINNESOTA RUBBER QUAD RING

The VQ4273 is an AS568-273 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 9.734 in (247.24 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.012 in (254.3 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Expect good resistance to petroleum oils and fuels, aggressive chemicals, and many acids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

Common environments for this compound include automotive fuel systems, high-temperature process equipment, and semiconductor equipment.

Reference part number VQ4273 when ordering; the item is sold individually. Nominal inside diameter is listed as 9 3/4. 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.
