G71029-90 is a precision-machined aerospace engine exhaust nozzle seal ring, compliant with AS9100D quality standards and FAA/EASA regulations, optimized for CFM56 and IAE V2500 turbofan engines. It seals the clearance between the exhaust nozzle's movable and fixed components, minimizing the leakage of high-temperature exhaust gases, maintaining the nozzle's thrust conversion efficiency, and ensuring stable engine thrust output across idle, climb, cruise, and takeoff phases.

Crafted from a heat-resistant nickel-based superalloy with an anti-oxidation coating, it withstands operating temperatures up to 950°C and thermal shock. Weighing 0.65kg with a precision-fit modular design, it enables fast replacement during exhaust section MRO overhauls. FAA Part 25 certified, it is a key component for exhaust system efficiency and engine performance stability.
