The Leak Sealant You Can Count On

More Than Three  Million Units Sold

The 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 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.

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.
