## 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.

It does not work

### ⭐⭐⭐⭐⭐ Review
*by J***I on 24 September 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.
