98F32204000000 is a precision aviation maintenance tool compliant with AS9100D quality standards and FAA/EASA regulations, dedicated to aircraft engine fuel system maintenance.It functions as a fuel pipeline flaring tool, specialized in processing the flared ends of aviation fuel pipeline during MRO assembly and repair. It creates precise, uniform flares to ensure tight, leak-proof connections with matching fittings, preventing fuel leakage that could trigger fire hazards or engine fuel supply interruption during flight.Made of high-strength chrome-vanadium alloy steel with heat treatment, it resists wear and deformation, working stably at -55℃ to 200℃. Weighing 0.42kg, its compact structure suits narrow engine bays, enabling accurate one-step flaring operation. It is a critical tool to standardize fuel pipeline connections and ensure aircraft engine fuel system safety and reliability.
