4MM CS X 80MM ID BLACK FKM 75D

V4X80 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 80 mm (3.15 in), a cross section of 4 mm (0.157 in), and an outside diameter of 88 mm (3.46 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to petroleum oils and fuels, chlorinated solvents, and many acids. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with hot water and steam or amines.

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

V4X80 ships individually. Unit weight is approximately 6.175 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
