C29006-34 is a precision-engineered aerospace engine low-pressure turbine (LPT) 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 LPT rotor and the engine casing, reducing the leakage of exhaust gases from the turbine section, which helps maintain the turbine's operating pressure, improves energy utilization efficiency, and supports stable thrust output across idle, climb, cruise, and takeoff phases.

Crafted from a heat-resistant nickel-based superalloy with a low-friction, anti-oxidation coating, it withstands operating temperatures up to 820°C and high-velocity gas impacts. Weighing 0.72kg with a precision-machined mating surface, it allows quick alignment and replacement during hot-section MRO overhauls. FAA Part 25 certified, it is a key component for LPT system efficiency and engine operational durability.
