856A1815 is a modular hydraulic system test kit, compliant with AS9100D aerospace quality standards and FAA AC 43.13-2B regulations, engineered for comprehensive testing of commercial aircraft hydraulic systems across Boeing 737 MAX, 777X and Airbus A320neo, A350 fleets.

Constructed from aerospace-grade aluminum alloy with hard-anodized and stainless steel components, it withstands operating pressures up to 5,000 psi and temperatures from -40°C to 150°C, suitable for hangar and flight line use. The kit integrates digital pressure transducers (±0.2% accuracy), flow meters, and adjustable regulators to test hydraulic valves, actuators, and lines. Its modular design allows customization for landing gear, flight control, and brake systems, making it a versatile core tool for MRO teams to diagnose hydraulic faults and ensure system integrity.
