5MM CS X 56MM ID BLACK FKM 75D

V5X56 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 56 mm (2.205 in), a cross section of 5 mm (0.197 in), and an outside diameter of 66 mm (2.6 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against engine and transmission fluids, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is specified for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -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.

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