JXHK-GB-1356 is a professional aviation maintenance tool compliant with AS9100D standards and FAA/EASA regulations, tailored for commercial aircraft environmental control systems (ECS) and ground support maintenance. Crafted from high-strength corrosion-resistant alloy with anti-rust coating, it withstands -55℃ to 140℃, resisting coolant erosion and mechanical wear for stable, durable performance in frequent MRO tasks. Specialized in disassembling, installing and calibrating ECS air valves, coolant line connectors and cabin air duct joints, it features precision-machined non-damaging jaws with tight tolerances to prevent seal damage and air leakage, critical for stable cabin temperature and air pressure. Its compact, ergonomic design fits confined ECS compartments, matches mainstream Airbus & Boeing ECS specs, streamlines servicing workflows, cuts ground downtime, safeguards ECS integrity, and is an indispensable tool for aircraft cabin comfort and overall operational safety.
