C21007-74 is a precision-manufactured aerospace engine hydraulic system seal component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It seals the connection positions of the engine hydraulic pipeline and actuator components, preventing the leakage of hydraulic oil, which is critical for maintaining the stability of hydraulic system pressure, ensuring the accurate operation of engine control mechanisms such as thrust reversers and variable stator vanes, and avoiding system failure caused by hydraulic fluid loss.

Made from high-strength, oil-resistant and heat-resistant nitrile rubber composite, it withstands operating temperatures from -40°C to 180°C and long-term contact with aviation hydraulic oil. Weighing 0.047kg with a precision-machined sealing structure, it allows for fast installation and tightness verification during hydraulic system MRO overhauls. FAA Part 25 certified, it is a key component for engine hydraulic system safety.
