The Tracerline TP-8627 EZ-Ject Leak Detection Kit from Tracer Products helps technicians pinpoint leaks in air-conditioning and fluid systems with a powerful Opti-Lite high-intensity, 6-LED blue light flashlight that the company says makes even small leaks clearly visible. The kit includes a universal A/C dye cartridge that services up to 14 vehicles; plus dye for oil, fuel, ATF, power steering and hydraulic systems; a coolant dye; spray bottle of dye cleaner; and fluorescence-enhancing glasses in a sturdy plastic carrying case.
