Spectroline's AD-8609 Aero-Brite Universal Fluorescent Leak Detection Dye pinpoints the exact source of all fuel, lubrication and hydraulic leaks in aviation systems. Adding the dye is a simple procedure. Pour a small amount of the super-concentrated dye into the aircraft fluid 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 leak detection lamp and a bright yellow/green glow will show the precise location of every leak. Aero-Brite dye is specially formulated to work with anypetroleum and synthetic-based host fluid and meets Mil Spec MIL-PRF-81298E, Type III, Yellow/Green Fluorescent for aircraft fuel systems. It will not damage the fluid’s properties or any of the system’s components. Aero-Brite allows inspection of the entire system under most operating conditions, and is ideal for both in-flight and static testing. It is available in 8- (237 ml), 16- (473 ml) and 32-ounce (946 ml) bottles, and 1-gallon (3.8 L) containers. For more information call (800) 274-8888.
