The SpectrolineALK-365 Aviation Fluid Leak Detection Kit is the most complete kit for finding leaks in aviation fuel, lubrication and hydraulic systems and works with all petroleum- and synthetic-based lubricants and fluids. This reliable kit prevents expensive equipment breakdown and potential safety hazards. At the heart of the ALK-365 kit is the powerful, cordless and rechargeable OPTIMAX 365 UV leak detection flashlight. Engineered with state-of-the-art, ultra-hi-flux LED technology, this flashlight is four times brighter than other high-intensity UV lamps. The kit also includes an 8-ounce (237 ml) bottle of Aero-Brite universal fluorescent dye, which pinpoints the exact location of all aviation fluid leaks by a bright yellow/green glow.
