956A6054G02 is a precision-engineered aerospace engine low-pressure turbine (LPT) blade platform seal, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 series turbofan engines. It seals the gap between the LPT blade platform and the turbine shroud, reducing the leakage of the low-temperature, low-pressure gas that has passed through the HPT, which is critical for maintaining the LPT's energy conversion efficiency, reducing energy waste, and ensuring stable power output of the turbine system.

Made from a heat-resistant, wear-resistant nickel-based superalloy, it withstands operating temperatures up to 920°C and continuous gas flow impact. Weighing 0.11kg with a precision-machined mating surface, it allows for fast installation and leak verification during LPT MRO overhauls. FAA Part 25 certified, it is a key component for LPT performance and engine operational safety.
