Review: FIX YOUR AC UNIT SMALL LEAK - if you have a small ac leak you can slow it down or fix it until you can get something better. you will need a hose to add freon gas to whatever you are working on , R-22,R-410a, R-134a or whatever does not matter, you can mix freon, just add a little at a time the gases expand at different rates, to much no good. get the hose, get the freon gas, you may need an ADAPTOR to screw this sealer injection shot onto the input port on the ac unit you are attempting to seal, first you should try putting a little freon into the system if you hear it just blow right out ,you should try to close the hole ,solder or band clamp with rubber this is only effective on smaller than a pinhole ,works good, if I have a unit that leaks down after 6 months it will pretty much fix it, I keep 2 in my ac repair box always, as always I recommend watching a DYI video before you use this , Enjoy
Review: Easiest way to save both dollars and the environment by stopping refrigerant leaks - Super easy to use and well-packaged.

## Features

- STOP LEAKS PERMANENTLY - The Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 7 days. 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
- WORKS WITH ALL SYSTEMS INCLUDING CARS - Our product is compatible with all systems, refrigerants (except ammonia), car refrigerants, and oils. It is great for central air conditioners, 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
- STRAIGHTFORWARD INSTALLATION - No more fussing with messy syringes, hoses, or pressurized cans. The Leak Saver HVAC sealant 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. You can see our straightforward installation videos below
- SAFE FOR ALL TOOLS AND PARTS - Our HVAC leak sealer is safe for all manifold gauges, hoses, expansion valves (TXVs, TEVs, capillary tubes, etc), Schrader valves, and anything needed to service your system. Adapter required for mini splits (5/16" to 1/4") and automotive systems ( 134A to 1/4")
- THE MOST TRUSTED - The numbers don’t lie! With more than 4,000,000 units sold of our air conditioner leak sealer formula since 2015, we are the most trusted leak sealant among HVAC professionals. Proudly made in the USA. We stand 100% behind the quality of our products. If for any reason you are not satisfied with your order, reach out to 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.

### ⭐⭐⭐⭐⭐ Easiest way to save both dollars and the environment by stopping refrigerant leaks
*by J***K on September 7, 2025*

Super easy to use and well-packaged.

### ⭐ Not a "Wonder Fix" as I hoped
*by W***. on September 10, 2025*

I have a small and slow coolant leak in our wine frig. The system is small (1.8 oz of 134a) and I hoped that this would solve the problem. I recharged the system and used the product, but the leak persisted and the frig lost temperature again over the same period of time (about 3 days). I bought and tried a second application and still no success. After investing about $100 for the injector and the two treatments, I really hoped this would be a cost-effective fix. Time to research some other products in hope to avoid replacing the frig.
