Part number V4X41 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 41 mm (1.614 in), a cross section of 4 mm (0.157 in), and an outside diameter of 49 mm (1.93 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The material holds up against chlorinated solvents, aromatic hydrocarbons, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in ketones and esters or low-molecular-weight organic acids.
Maintenance and OEM teams specify it across chemical processing, automotive fuel systems, and oil and gas.
