Aerospace applications demand FFKM O-rings for fuel systems and hydraulics, resisting jet fuels like JP-8 and Skydrol fluids. Seals in turbine engines operate at 300°C, preventing fires from leaks. Their low volatility suits space missions, as in NASA's Orion capsule. FFKM's radiation resistance protects against cosmic rays. Compared to silicone, it avoids swelling in aromatic hydroca... https://globalsealstech.com/ffkm-seals/
