- THE EASIEST INJECTION METHOD: No more fussing with messy syringes, hoses, or pressurized cans. 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. Note: for automotive systems, you will still need the standard 134A to 1/4” charging adapter. Mini-splits may require a 5/16” to 1/4” charging adapter.
- 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. When a leak occurs, the Leak Saver reacts with the air and moisture at the leak site to permanently seal the leak. When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks.
- 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.
- COMPATIBLE WITH ALL SYSTEMS AND REFRIGERANTS: : The Leak Saver UV is compatible with all systems, refrigerants (except ammonia), and oils. It is great for central air conditioners, car and automotive air conditioners, refrigerators, ductless mini-splits, heat pumps, geothermal heat pumps, commercial refrigeration systems, micro channel coils and more. It also works with all refrigerants including R410A Freon, R22 and replacements, R134A, r1234yf, R404A, R290, R600a, and more.
- YOUR SATISFACTION IS OUR PRIORITY: We stand behind the effectiveness 100%. If for any reason you are not satisfied with your product, please contact us and we will make it right.
