**4019-514AD MINNESOTA RUBBERQUAD RING

Part number VQ4019 is an AS568-019 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 0.801 in (20.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.941 in (23.9 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified for excellent resistance to compression set and permeation, outstanding high-temperature capability. The compound resists engine and transmission fluids, chlorinated solvents, and many acids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where hot water and steam or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across high-temperature process equipment, chemical processing, and semiconductor equipment.
