Fix AC Leaks Fast: LF200CS Single-Use Sealant for DIYers
If you’re a hands-on driver or an aftermarket pro, you don’t need complicated tools to stop slow A/C leaks. Tracer Products’ LeakFinder® LF200CS AC leak sealant gives you a fast, reliable way to seal pesky micro-leaks with a single-use syringe injector and a patented dual adapter that works on both R-134a and R-1234yf systems. It’s purpose-built for DIY convenience—and proven for shop use.
Why DIYers and the Aftermarket Love This AC Leak Sealant
The LF200CS permanently seals pinhole leaks in evaporators, condensers, accumulators/receivers, O-rings, and hoses—the exact places where small losses add up to warm air and repeat comebacks. The non-polymer, oil-soluble formula is safe for system components and recovery equipment, and it’s compatible with all popular refrigerants, including R-1234yf. It’s also hybrid/EV compatible, so you can service modern vehicles with electrically driven A/C compressors. That’s broad coverage with one product.
For DIY users, the single-use syringe means no guesswork and no mess—just connect to the low-side service port with the included adapter, inject, and you’re done. For retailers and service writers, it’s a shelf-ready solution that moves quickly and keeps customers cool without tying up a bay. The LF200CS services one vehicle (any size), making it a convenient, confidence-building add-on for parts counters and mobile techs.
How It Works—and Why It’s Safe
When LF200CS circulates, it seeks out pressure/temperature differentials at the leak point. There, it coagulates and forms a pliable, web-like internal seal—stopping the loss and restoring performance. Because the formula is non-hardening et A/C-machine safe, it won’t gum up RRR equipment or restrict free-flowing components. It’s a practical, permanent fix for the slow, hard-to-find leaks that traditional methods can miss.
Setup is simple:
ADAPT to your refrigerant (R-134a or R-1234yf) → CONNECTER to the low-side port → INJECT the sealant. Always ensure the system has enough refrigerant to circulate the product and follow the instructions included with the kit. That’s professional-grade sealing—no specialized tools required.
Built for Aftermarket Success
From DIY aisle to service desk, LF200CS checks every box: it’s safe and easy to use, tackles leaks across multiple A/C components, and is made in the USA. Tracer Products backs the solution with clear instructions and packaging options suited to counter or slat-wall displays, helping shops and retailers stock a high-turn product customers can trust.
Bottom line: If you want an AC leak sealant that matches OEM-level safety with true DIY simplicity, choose the LeakFinder® LF200CS. Seal the leak, save the day—and get back to cool.
