RRT087442-1 is a precision aerospace component compliant with AS9100D quality standards and FAA/EASA aviation regulations, dedicated to aircraft engine fuel supply systems.It acts as a high-efficiency aviation fuel filter element, a core purification part for engine fuel lines during MRO replacement. It effectively captures micro-impurities, metal debris and contaminants in aviation fuel, prevents fuel injector and nozzle clogging, avoids poor atomization and incomplete combustion, and protects critical fuel system components from abrasive wear to maintain stable engine power output.Made of high-performance filter media with a corrosion-resistant aviation-grade stainless steel framework, it resists fuel erosion and high temperature, working stably at -55℃ to 210℃. Weighing 0.11kg, it features compact structure, high filtration efficiency and quick replacement design. It is a critical component to ensure fuel system cleanliness and overall aircraft engine operational safety and reliability.
