HIX5002-0G is a precision-manufactured aerospace engine accessory gearbox seal component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It seals the connection positions between the accessory gearbox and other engine components, preventing the leakage of lubricating oil and the intrusion of external dust and foreign matter, which is critical for maintaining the cleanliness of the gearbox's internal lubrication system, ensuring the stable operation of transmission parts, and avoiding abnormal wear or failure of the accessory gearbox.

Made from high-strength, oil-resistant and heat-resistant polymer composite material, it withstands operating temperatures up to 180°C and continuous friction. Weighing 0.045kg with a precision-machined sealing structure, it allows for fast installation and tightness verification during gearbox MRO overhauls. FAA Part 25 certified, it is a key component for accessory gearbox operational safety.
