Tracer Products is proud to announce the launch of its newest innovation: LeakFinder® A/C Recharge with Leak Stop + UV Dye. Available now in part numbers LF134 and LF134H (with reusable hose), this all-in-one solution combines the power of refrigerant recharge, leak sealing, and UV dye detection into a single professional-grade can.
Why This Launch Matters
Air conditioning leaks are among the most common issues drivers face, yet they’re also one of the hardest to detect and repair. Small leaks in O-rings, hoses, evaporators, and condensers can cause reduced cooling, higher energy consumption, and costly repairs. With today’s hybrid and EV systems becoming more complex, technicians and DIY car owners alike need solutions that are safe, effective, and trusted.
That’s why the launch of LeakFinder® LF134 and LF134H is a game-changer.

The 3-in-1 Benefits of LeakFinder®
This new product was designed to solve multiple A/C problems at once:
- Refills Refrigerant – Restores cooling performance by adding R-134a refrigerant directly into the system.
- Seals Small Leaks – Professional-grade, non-hardening sealant targets leak sites and creates a durable internal seal.
- Includes UV Dye – Meets SAE J2297 standards, making it easy to locate future leaks quickly with a UV light.
This combination ensures immediate results and long-term reliability—making LeakFinder® stand out from ordinary recharge kits.
