The Tracerline TP-8626 EZ-Shot Kit is a complete A/C leak detection kit that the manufacturer says makes it easy for technicians to spot all air conditioning leaks fast and efficiently. The kit features the Opti-Lite, a compact, cordless, 6-LED blue light leak detection flashlight that can get into areas inaccessible to larger lamps. Also included in the kit are an EZ-Shot A/C dye injection gun with hose and coupler, an 8-ounce BigEZ universal dye cartridge for all A/C systems (treats up to 64 vehicles), an 8-ounce spray bottle of Glo-Away dye cleaner, fluorescence-enhancing glasses and underhood labels. All components are stored in a rugged plastic carrying case.
