## Description

Three Million Units Sold and Counting!We are a company founded and actively managed by HVAC technicians. Our goal is to bring you the best Leak Sealants and tools that we use ourselves on our daily jobs. We have literally tried everything! These are the products we stand behind 100%. The Most Reliable Leak Sealant in the Market The numbers don’t lie! With more than 3,000,000 units sold of this sealant formula since 2015, we are the most reliable leak sealant among HVAC and Refrigeration professionals. Proudly made in the USA. We believe in the effectiveness of our product and stand behind it 100%.The Leak Sealant You Can Count OnMore Than Three Million Units SoldThe Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 72 hours. It works similarly 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. Patent-Pending Easy Direct Injection Installation MethodNo 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.Have a leak too big for sealants? Find it with the added UV dye!Some leaks are just too large to be sealed by any leak sealant. Now, thanks to the added UV dye, even if you have a large leak, the UV dye will help you find the leak hole. Simply shine a UV light and the UV dye will illuminate brightly at the site of the leak. This is a great added security when troubleshooting leaky systems.

Review: Had a leak last year. Used this after refilling to try to last for another summer and so far it held up a year later! I have stopped using the heating cycle to prevent useless thermal stress and extend it as far as possible. I tried to cheap out buying this and a manual pump and adapters and whatnot. TLDR: Don't cheap out and get the Co2 injector too.

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.

*by H***. on 14 July 2024*

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
