9426M13G01 is a precision-manufactured aerospace engine low-pressure compressor (LPC) seal segment, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a key sealing component in the LPC, isolating the compressed air in the LPC flow path from the engine's inner cavity, which is critical for maintaining the pressure stability of the LPC flow path, ensuring the compression efficiency of the LPC, and avoiding air leakage that would reduce the air supply for the subsequent HPC and combustion chamber.

Made from high-strength, anti-corrosion aluminum alloy with surface anti-oxidation treatment, it withstands operating temperatures from -50°C to 180°C and continuous scouring from high-speed air flow. Weighing 0.27kg with a precision-machined sealing surface, it allows for fast replacement and tightness inspection during LPC MRO overhauls. FAA Part 25 certified, it is a key component for LPC operational stability.
