A71023-56 is a precision-manufactured aerospace engine combustion chamber liner seal, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 series turbofan engines. It seals the circumferential joint between combustion chamber liner segments, blocking high-temperature, high-pressure combustion gas from leaking into the engine casing area, which is critical for maintaining the internal pressure of the combustion chamber, ensuring complete fuel combustion, avoiding overheating of the outer engine structure, and reducing fire risks.

Made from heat-resistant, oxidation-resistant nickel-based superalloy with a flexible sealing structure, it withstands operating temperatures up to 1520°C and continuous thermal shock. Weighing 0.12kg with a precision-machined mating surface, it enables fast replacement and tightness verification during combustion system MRO overhauls. FAA Part 25 certified, it is a key component for combustion system safety.
