956A8005G01 is a precision-engineered aerospace engine low-pressure turbine (LPT) disk seal, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 series turbofan engines. It seals the axial gap between the LPT disk and the adjacent turbine casing, minimizing the leakage of expanded, low-pressure exhaust gas that has passed through the turbine stages, which is critical for maintaining the LPT's energy conversion efficiency, reducing 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 960°C and continuous gas flow impact. Weighing 0.18kg with a precision-machined sealing surface, it enables fast installation and leak verification during LPT MRO overhauls. FAA Part 25 certified, it is a key component for LPT performance and engine operational stability.
