As a material, Fluorosilicone (FVMQ) is widely chosen for the standard choice for static aerospace fuel system seals and silicone's low-temperature flexibility combined with fuel resistance. This material stands up to extreme cold, aromatic fuels and jet fuel, and ozone and weathering. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C). It is not the right choice where brake fluids or hydrazine are present.
It sees regular use in military ground vehicles, aviation fuel systems, and high-altitude equipment.
