856A4055G14 is a specialized ground support tool for aircraft hydraulic system maintenance, engineered to AS9100D quality standards and FAA/EASA MRO regulations, optimized for narrow-body fleets like Boeing 737 MAX and Airbus A320neo. It facilitates efficient flushing, pressure testing, and fluid transfer for landing gear, flight control, and brake hydraulic circuits during overhaul and troubleshooting.

Constructed from corrosion-resistant stainless steel and aerospace-grade aluminum, it features a 15L fluid reservoir, variable-pressure pump (0–5,000 psi), quick-connect aviation fittings, and a digital pressure gauge (±0.1% accuracy). Integrated filtration (10μm) removes contaminants, while anti-leak valves prevent fluid waste. Weighing 28kg and measuring 750×450×600mm, it complies with RTCA DO-160G, streamlines hydraulic system servicing, reduces contamination risks, and cuts aircraft on-ground time for commercial airlines.
