Review: Novice Installer - 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.
Review: Easy to use for DIYer - Easy to use for DIY. Wasn't sure whether I had a leak, but decided to use it in case there was, and if not it is in the system in case a leak were to develop, so it can potentially self heal. Good instructions, just needed a piercing valve and to borrow a vacuum pump and manifold gauge set from my son.

## 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.

## Questions & Answers

**Q: Will this work with my system?**
A: The Leak Saver works with all air conditioner and refrigeration systems. It is compatible with all refrigerants (except ammonia) and is compatible with all oils.

**Q: How does the Leak Saver work?**
A: After injection, The Leak Saver sealant circulates throughout the system with the refrigerant. If there is a small leak, the sealant reacts with the moisture and oxygen at the leak site to form a permanent "scab-like" seal.

**Q: What do I need to install the Leak Saver?**
A: To inject the Leak Saver, you will need either a basic set of manifold gauges or our Leak Shot injector. When using it with automotive systems, you will need a 134a to 1/4” adapter. Ductless mini-split systems may require a 5/16” to 1/4” adapter.

**Q: What size leak will the Leak Saver seal?**
A: The Leak Saver is able to seal small refrigerant leaks where the complete charge is not lost within 7 days. If this is not possible, your leak is too large to be repaired with Leak Saver.

**Q: What do I do if it doesn’t work?**
A: We stand behind the effectiveness. If you are not completely satisfied, please reach out to us directly and we will make it right. With more than 4 million units of this formula sold since 2015, we have a strong track record of effectiveness.

### ⭐⭐⭐⭐⭐ Less work to fix small Freon leaks than hunting the leak
*by L***S on October 21, 2023*

I'd been trying to locate a small Freon leak with soap sprays, oil residue searches, & Freon sniffers on the 7-year old split unit heat pump in my shop. It would run for 4 to 5 months of cooling & heating, then suddenly shut down with low pressure indicated. It tended to run longer cooling than when heating. I was leary of stop-leak products in general because of bad experiences in car systems; the stuff plugged up everything (like thermostats) as well as the intended target. The R-410A systems run at very high pressures compared to old R-22 systems so I expected to find a fitting not quite tight enough to hold the refrigerant. No luck. I viewed the clear tubing holding the stop leak & UV dye with suspicion--didn't look strong enough to hold the high pressure. The connectors fit perfectly (I already had the adapter on the low-pressure line needed to connect the low-pressure hose); they were just like an extension of the charging hose. I decided to do the injection & recharge in one go. I set up liquid injection into the low-pressure line to make sure the contents were diluted promptly. When I opened the tank charging valve the yellow fluid in the clear tubing vanished immediately followed by boiling R-410A. I watched while the scales moved smoothly up to the 68.8 oz charging spec with the system running on cooling. Everything worked fine for about an hour then the system shut down. Turned out there was more residual R-410A than I expected & the system stopped (high pressure cutoff) when the fluid temperature came up to the 100 deg F outside temperature. I decided to let the system pressure equalize--give the leak a chance to expel some of the stop leak fluid. Air & moisture was suppose to cause it to harden & plug the leak. Sure enough, the next day the AC came on & the air coming out of the evaporator was a chilly 50 deg F. It has worked great both as a heat pump & AC since then. I haven't tried to located my UV light to see if any dye escaped. I expect that will be easier to find if significant R-410A escapes in a few months. Follow the instructions; I recommend this for small leaks--don't waste R-410A (or any other refrigerants) trying to plug large leaks. The dye-only version is probably your best approach in that case.
