Aerospace applications demand seals that withstand JP-8 fuel, Skydrol hydraulic fluid, and hot engine oils simultaneously. FFKM O-rings in fuel injectors and hydraulic actuators maintain sealing performance after thousands of hours at 260°C while resisting aromatic hydrocarbons that swell and degrade standard fluorocarbon elastomers within minutes of exposure. https://globalsealstech.com/ffkm-seals/
