Fluorosilicone (FVMQ) delivers silicone's low-temperature flexibility combined with fuel resistance and the standard choice for static aerospace fuel system seals. The compound resists chlorinated solvents, aromatic fuels and jet fuel, and petroleum oils. Service temperature is rated from -80°F (-62.2°C) through 350°F (176.7°C). Applications involving hydrazine or ketones call for a different compound.

It sees regular use in high-altitude equipment, military ground vehicles, and aerospace and defense.
