3. Leak Saver

Leak Saver: Direct Inject UV, Refrigerant Leak Sealer with Added UV Dye to Detect Large Leaks, Compatible with All Refrigerants, for AC, Refrigeration, and Automotive Systems Up to 5 Tons

#ad
Leak Saver #ad - Compatible with all systems and refrigerants: : the leak saver uv is compatible with all systems, and oils. Note: for automotive systems, hoses, you will still need the standard 134A to 1/4” charging adapter. The leak saver injects directly and easily into the system with a basic manifold gauge set or even easier with our Leak Shot Injection Kits.

If for any reason you are not satisfied with your product, please contact us and we will make it right. It is great for central air conditioners, R404A, heat pumps, micro channel coils and more. The easiest injection method: no more fussing with messy syringes, or pressurized cans. When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks. Mini-splits may require a 5/16” to 1/4” charging adapter. Your satisfaction is our priority: we stand behind the effectiveness 100%. When a leak occurs, the leak Saver reacts with the air and moisture at the leak site to permanently seal the leak.

More than 3 million units sold since 2015: the leak saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 72 hours. It also works with all refrigerants including r410a freon, r600a, refrigerators, R1234yf, car and automotive air conditioners, ductless mini-splits, R290, R22 and replacements, R134A, geothermal heat pumps, refrigerants except ammonia, commercial refrigeration systems, and more. It’s similar to how blood in your body reacts to a cut.
