4MM CS X 320MM ID BLACK FKM 75D

Part number V4X320 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 320 mm (12.598 in), a cross section of 4 mm (0.157 in), and an outside diameter of 328 mm (12.91 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) is valued for very low compression set at elevated temperature and outstanding high-temperature capability. This material stands up to engine and transmission fluids, chlorinated solvents, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

It sees regular use in aerospace, semiconductor equipment, and automotive fuel systems.
