4108-514AD MINNESOTA RUBBER QUAD RING

Part number VQ4108 is an AS568-108 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 0.237 in (6.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.443 in (11.25 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Expect good resistance to aromatic hydrocarbons, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is specified for outstanding high-temperature capability and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and aerospace.
