Aero-Brite Universal Fluorescent Leak Detection Dye from Spectronics Corp. is a quick and easy way to pinpoint the exact source of all fuel, lubrication and hydraulic leaks in aviation systems. Simply add a small amount of super-concentrated Aero-Brite dye to the aircraft system and let it circulate. The dye/fluid mixture will accumulate at even the smallest leak sites. Scan the area with a Spectrolinehigh-intensity UV inspection lamp and a bright green glow will show the precise location of every leak. It is specially formulated to work with any petroleum- and synthetic-based host fluid. It will not damage the fluid’s properties or any of the system’s components.
