Developed for R134a air conditioning systems, this PAG dye tracer stick circulates fluorescent solution to identify the exact source of leaks under ultraviolet light. The stick connects via two control valves to tap the system, allowing the dye to enter the refrigerant stream. For ports in restricted areas, whip hoses may be necessary to facilitate the injection.
