4MM CS X 115MM ID BLACK FKM 75D

V4X115 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 115 mm (4.528 in), a cross section of 4 mm (0.157 in), and an outside diameter of 123 mm (4.84 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists aggressive chemicals, chlorinated solvents, and many acids. Viton® (FKM) is widely chosen for outstanding high-temperature capability and very low compression set at elevated temperature. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across high-temperature process equipment, semiconductor equipment, and oil and gas.
