956A8078G01 is a precision-manufactured aerospace engine high-pressure turbine (HPT) seal plate, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 series turbofan engines. It creates a sealed barrier between the HPT's stationary and rotating components, minimizing the leakage of high-temperature, high-pressure combustion gas, which is critical for maintaining the turbine's thermal efficiency, reducing energy loss, and preventing overheating of adjacent engine parts.

Made from a heat-resistant, corrosion-resistant nickel-based superalloy, it withstands operating temperatures up to 1380°C and intense thermal stress. Weighing 0.37kg with a precision-machined sealing surface, it enables fast installation and leak verification during HPT MRO overhauls. FAA Part 25 certified, it is a key component for HPT performance and engine operational safety.
