*4363-514AD MINNESOTA RUBBER QUAD RING

Ordered as VQ4363, this is an AS568-363 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 6.475 in (164.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.895 in (175.13 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

It resists engine and transmission fluids, petroleum oils and fuels, and chlorinated solvents. Viton® (FKM) is known for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with ketones and esters or hot water and steam.

You will find this material specified across oil and gas, automotive fuel systems, and high-temperature process equipment.

VQ4363 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. 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.
