Fluorosilicone (FVMQ) is widely chosen for good compression set resistance in static duty and silicone's low-temperature flexibility combined with fuel resistance. Expect good resistance to aromatic fuels and jet fuel, petroleum oils, and ozone and weathering. Rated temperature range runs from -80°F (-62.2°C) to 350°F (176.7°C) in continuous service. Verify compatibility before use with hydrazine or ketones.
It sees regular use in aerospace and defense, aviation fuel systems, and military ground vehicles.
