Tracer Products has developed a fluorescent dye, TP-3405CS Dye-Lite All-In-One, improves leak detection in all oil and oil-based fluid systems. It is effective with all UV and blue light lamps. TP-3405CS Dye-Lite All-In-One dye contains two fluorescent dyes. One fluoresces best under UV and the other under blue light.
The dye is circulated through the vehicle’s fluid system and will escape with the host fluid through the small leaks. When the system is scanned with a high-intensity Tracerline UV lamp, the dye will glow, spotlighting the exact location of every leak. All-In-One is available in standard and concentrated formulas.
