A71023-53 is a precision-manufactured aerospace engine combustion chamber inner liner seal, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 series turbofan engines. It seals the joints between the segments of the combustion chamber inner liner, blocking the direct contact between high-temperature combustion gas (up to 1650°C) and the outer combustion chamber structure, which is critical for reducing heat transfer to the engine's external components, preventing overheating and structural deformation, and maintaining the integrity of the combustion space.

Made from heat-resistant, oxidation-resistant nickel-based superalloy with a flexible sealing structure, it withstands continuous thermal shock and gas scouring. Weighing 0.14kg with a precision-machined mating surface, it allows for fast installation and tightness verification during combustion system MRO overhauls. FAA Part 25 certified, it is a key component for combustion system safety.
