Part number V5X20 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 20 mm (0.787 in), a cross section of 5 mm (0.197 in), and an outside diameter of 30 mm (1.18 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Viton® (FKM) is specified here for very low compression set at elevated temperature and industry benchmark where nitrile reaches its thermal limit. The material holds up against chlorinated solvents, aggressive chemicals, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or amines call for a different compound.
Maintenance and OEM teams specify it across high-temperature process equipment, automotive fuel systems, and oil and gas.
Stocked as V5X20 and sold individually. Unit weight is approximately 2.8046 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
