4MM CS X 13MM ID BLACK FKM 75D

The V4X13 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 13 mm (0.512 in), a cross section of 4 mm (0.157 in), and an outside diameter of 21 mm (0.83 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against chlorinated solvents, engine and transmission fluids, and petroleum oils and fuels. Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across oil and gas, aerospace, and chemical processing.
