This material stands up to ozone and weathering, aromatic fuels and jet fuel, and extreme cold. Fluorosilicone (FVMQ) offers excellent ozone and UV stability, a very wide service temperature range. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C). It should not be specified for service in high-temperature dynamic service or hydrazine.

Maintenance and OEM teams specify it across aviation fuel systems, high-altitude equipment, and military ground vehicles.
