Leak Saver
- THE SIMPLEST INJECTION METHOD: No more fiddling with syringes, hoses, or pressurized cans. With a basic manifold gauge set or even easier with our Leak Shot Injection Kits, the Leak Saver injects directly and easily into the system. Please keep in mind that the standard 134A to 1/4″ charging adapter is still required for automotive systems. A 5/16″ to 1/4″ charging adapter may be required for mini-splits.
- SINCE 2015, MORE THAN 3 MILLION UNITS HAVE BEEN SOLD: When the entire refrigerant charge is not lost within 72 hours, the Leak Saver can permanently seal small refrigerant leaks. It’s similar to how blood reacts to a cut in your body. When a leak occurs, the Leak Saver reacts with the surrounding air and moisture to permanently seal the leak. The active ingredient circulates safely in the system to seal future leaks when used for preventative maintenance.
- WITH UV DYE ADDED FOR FINDING LARGE LEAKS: Either 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 illuminate the leak site brightly when using a UV flashlight.
- COMPATIBLE WITH ALL SYSTEMS AND REFRIGERATING MATERIALS: All systems, refrigerants (except ammonia), and oils are compatible with the Leak Saver UV. It works well in central air conditioners, car and automotive air conditioners, refrigerators, ductless mini-splits, heat pumps, geothermal heat pumps, commercial refrigeration systems, micro channel coils, and other applications. It also works with R410A Freon, R22 and replacements, R134A, R1234yf, R404A, R290, R600a, and other refrigerants.
- OUR PRIORITY IS YOUR SATISFACTION: We fully support the effectiveness. If you are dissatisfied with your purchase for any reason, please contact us and we will make it right.
