Overview
The K35001-115 is a high-performance, flight-safety critical Crew Oxygen Flow Fuse Test fixture custom-engineered for the rigorous maintenance, calibration, and airworthiness auditing of the Boeing 787 Dreamliner oxygen distribution network. Classified as a specialized Ground Support Equipment (GSE) diagnostic asset, this hardware is purpose-built to simulate flight-condition pressure differentials and verify the mechanical triggering thresholds of the aircraft's oxygen flow-limiting fuses. Manufactured by JUNXUN to comply with strict Boeing 787 system safety specifications, the K35001-115 ensures that crew oxygen flow fuses will correctly identify and isolate rapid pressure drops or line ruptures, preventing gas depletion and guaranteeing immediate availability of life-support oxygen during emergency depressurization events.

Key Points
Precision Pressure Simulation: Engineered with high-fidelity pressure regulation to accurately test the flow-fuse shut-off response times, mimicking cabin decompression or line-failure scenarios.

Boeing 787 System Integration: Custom-fitted with proprietary connectors and interface ports that match the 787 Dreamliner oxygen system hardware standards, enabling rapid and reliable system connectivity.

Ruggedized GSE Metallurgy: Fabricated from oxygen-compatible, corrosion-resistant materials, ensuring the integrity of the test environment while preventing internal contamination of the oxygen system components.

Repeatable Calibration Accuracy: Designed for high-volume hangar usage, providing consistent, drift-free diagnostic results that satisfy the stringent regulatory safety audits for commercial long-haul aircraft.

Applications
Crew Oxygen System Airworthiness Checks: Deployed by avionics and life-support technicians during periodic aircraft maintenance to verify the correct functioning of flow fuses and emergency shut-off valves.

Oxygen Distribution Troubleshooting: Utilized within specialized maintenance bays to isolate suspected faulty flow fuses or leaking sections within the 787 high-pressure oxygen distribution lines.

Airlines Maintenance Tool Crib Logistics: Essential specialized GSE hardware for global 787 operators and third-party MRO facilities to maintain the highest levels of passenger and crew safety compliance.

K35001-115 is a precision pneumatic control component designed for aviation maintenance tools and ground support equipment, widely compatible with global commercial narrow‑body, wide‑body and regional aircraft fleets. Manufactured in full compliance with AS9100D aerospace quality standards and FAA/EASA pneumatic system regulations, it is machined from high‑strength, corrosion‑resistant aerospace aluminum alloy with a sealed, wear‑resistant surface. Engineered for stable air pressure regulation and low‑pressure‑loss airflow, it performs reliably in harsh airfield environments, resisting mechanical vibration, dust, moisture and extreme temperature fluctuations. With ultra‑tight dimensional tolerances and standard quick‑connect pneumatic ports, it enables direct, leak‑free integration into air tool stations, tire inflation carts and GSE pneumatic control modules, effectively improving operational stability, service life and safety of aircraft pneumatic maintenance systems worldwide.
