The VQ4160 is an AS568-160 black Viton® (FKM) 75 Shore A quad profile Quad-Ring supplied with an inside diameter of 5.237 in (133.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.443 in (138.25 mm). This quad-ring provides a dual sealing band on each contact face for improved reliability.
As a material, Viton® (FKM) is specified for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to aromatic hydrocarbons, chlorinated solvents, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.
Maintenance and OEM teams specify it across automotive fuel systems, aerospace, and oil and gas.
Stocked as VQ4160 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
