2C81463G02 is a precision-manufactured aerospace engine high-pressure compressor (HPC) seal segment, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core sealing part in the HPC, isolating the high-pressure compressed air in the HPC flow path from the engine's internal cavity, which is critical for maintaining the pressure stability of the HPC flow path, ensuring the compression efficiency of the HPC, and preventing high-pressure air from leaking and affecting the operation of other engine components.

Made from high-strength, heat-resistant and wear-resistant nickel-based superalloy, it withstands operating temperatures up to 850°C and continuous scouring from high-speed air flow. Weighing 0.32kg with a precision-machined sealing surface, it allows for fast replacement and tightness inspection during HPC MRO overhauls. FAA Part 25 certified, it is a key component for HPC operational stability.
