4MM CS X 18MM ID BLACK FKM 75D

Part number V4X18 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 18 mm (0.709 in), a cross section of 4 mm (0.157 in), and an outside diameter of 26 mm (1.02 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

You will find this material specified across oil and gas, chemical processing, and automotive fuel systems.
