956A6322G02 is a precision-manufactured aerospace engine low-pressure turbine (LPT) rotor seal ring, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It seals the gap between the LPT rotor and the engine static casing, reducing the axial leakage of exhaust gas in the turbine section, which is critical for maintaining the pressure difference required for the LPT's energy conversion, optimizing the turbine's work efficiency, and avoiding the reduction of engine thrust or the increase of fuel consumption caused by gas loss.

Made from heat-resistant, wear-resistant nickel-based superalloy, it withstands operating temperatures up to 945°C and continuous scouring from high-speed exhaust gas. Weighing 0.075kg with a precision-machined sealing surface, it allows for fast installation and tightness check during LPT MRO overhauls. FAA Part 25 certified, it is a key component for LPT operational reliability.
