3. Leak Saver


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

Leak Saver #ad - Note: for automotive systems, hoses, you will still need the standard 134A to 1/4” charging adapter. Compatible with all systems and refrigerants: the leak saver uv is compatible with all systems, and oils. 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, car and automotive air conditioners, refrigerators, ductless mini-splits, R404A, commercial refrigeration systems, R22 and replacements, heat pumps, R134A, micro channel coils and more. When a leak occurs, the leak Saver reacts with the air and moisture at the leak site to permanently seal the leak. 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. When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks.

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’s similar to how blood in your body reacts to a cut. With added uv dye for finding large leaks: seal it or find it! If you have a leak that is simply too large for leak sealants to seal, the added UV Dye will light up brightly at the leak site when using a UV flashlight. Mini-splits may require a 5/16” to 1/4” charging adapter. The easiest injection method: no more fussing with messy syringes, or pressurized cans.
