Review: It definitely WORKS ! - There's not much more I can say about a product that truly works. I replaced my outdoor compressor with R407C, a direct replacement for old R22 system. The coil was in the attic and almost impossible to reach comfortably. It is 25 + years old. This year, I was losing pressure, so I gave this a try. BOOM ! leak stopped immediately. I added more gas and at 90 degrees out, I'm pushing 68 indoors. Contrary to HVAC guys, this product works and at $37 a squirt, any other conversation is used car talk ! And so simple to do, I bought 2 more for other systems I have. TRY THIS FIRST, SAVE THE BS
Review: Get extra years out of your old AC system - This is the second batch of Refrigerant Leak Sealers that I've used. I was losing a lot of freon from 2 systems. The initial treatments stopped the leaks almost completely. After a couple of years, one system started to leak a little. Another treatment stopped that as well. Now it's several years later and another treatment has boths systems working great and leak-free. The HVAC company charges $100-$150 per treatment for a very similar product. My builder-grade AC systems are almost 20 years old. Ours is the only home in our development that hasn't had to replace the AC systems. You do need a a basic manifold gauge set or injection kit, but it's simple to use.

## Features

- 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.

### ⭐⭐⭐⭐⭐ Novice Installer
*by J***I on September 24, 2025*

As an HVAC novice but a buildings expert I can Highly recommend this product for its ease of installation and effectiveness. It worked as advertised sealing a small leak in my lineset. Was quoted $8k from a reputable repair company I was able to fix the leak and recharge myself. Ill note the device has a low loss fitting attached making it not only effective but safe to use for even a novice like me. You dont want to get frostbite from the refrigerant. Also the included diagram makes it fool proof.
