JXHK-GB-1230 is a precision aerospace component compliant with AS9100D quality standards and FAA/EASA aviation regulations, dedicated to aircraft ground support and airborne hydraulic systems.It acts as a high-pressure hydraulic quick coupling, a key connection part for hydraulic pipelines in aircraft maintenance and airborne fluid transfer systems during MRO operations. It enables fast, leak-free connection and disconnection of hydraulic circuits, withstands extreme working pressure and temperature variations, prevents hydraulic fluid leakage and external contamination, and ensures stable fluid transmission for flight control, landing gear and brake system maintenance.Made of corrosion-resistant aviation-grade alloy steel, it resists hydraulic fluid erosion and wear, working stably at -55℃ to 210℃. Weighing 0.15kg, it features self-sealing structure and secure locking design, with easy operation and high reliability. It is a critical hydraulic component to guarantee efficient aircraft maintenance and airborne system safety.
