856A2830G02 is a dedicated ground support tool for aircraft cabin oxygen system maintenance, engineered to AS9100D quality standards and FAA/EASA MRO regulations, optimized for narrow-body fleets like the Boeing 737 MAX and Airbus A320neo. It enables safe pressure testing, leak detection, and gas refilling of onboard oxygen cylinders and distribution lines during routine servicing and component overhauls.

Constructed from corrosion-resistant stainless steel and aerospace-grade aluminum, it features a precision pressure regulator (0–3,000 psi), digital leak detection gauge (±0.5 psi accuracy), quick-connect medical-grade fittings, and an integrated relief valve for safety. Its compact design (680×420×550mm, 22kg) enhances portability across maintenance bays. Compliant with RTCA DO-160G, it minimizes oxygen system downtime, eliminates contamination risks, and ensures cabin safety system reliability for commercial airline fleets.
