Aerospace hydraulic systems require seals that operate in extreme conditions, from -55°C to 135°C. Fluorocarbon and perfluoroelastomers (FFKM) are common due to chemical resistance and thermal stability. Low outgassing seals prevent contamination in vacuum conditions. Aerospace seals undergo rigorous testing for reliability, as failure can be catastrophic. Lightweight materials also r... https://globalsealstech.com/hydraulic-seals/
