J78023-102 is a precision-engineered aerospace engine low-pressure turbine (LPT) vane platform seal, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 series turbofan engines. It seals the gap between the LPT vane platform and the turbine shroud, minimizing the leakage of exhaust gas that has passed through the turbine stages, which is critical for maintaining the LPT's energy conversion efficiency, reducing unnecessary exhaust energy loss, and supporting consistent engine thrust output during all flight phases.

Made from a heat-resistant, wear-resistant nickel-based superalloy, it withstands operating temperatures up to 920°C and continuous exhaust gas scouring. Weighing 0.1kg with a precision-machined mating surface, it enables fast installation and gap verification during LPT MRO overhauls. FAA Part 25 certified, it is a key component for LPT operational reliability.
