What People are saying
I successfully used this on a troublesome 410A, LG eight point mini split (48,000btu). I now use it in all new installations.

As a HVAC contractor I have started using this product over other sealants for a few reasons. Price is about half of what the other companies sell for. It’s super easy to install. And it comes with a dye so if the leak is to large you won’t have trouble finding it.

Excellent product, fixed Freon leaks. HVAC tech with 45 years experience will use again. Great company to do business with.

Used it on a number of older R22 AC units at rental properties. Has stopped the leaks in all of them. They were all difficult to find leaks either very small or internal to units, but large enough you would have to service the unit once or twice a year.

How Our Leak Saver® sealant works
Once injected into your A/C or refrigeration system, the Leak Saver works similarly to how blood works in your body. If there is a leak, the active ingredient will react with the air and moisture at the leak site to permanently seal the leak. Once the leak is sealed, it will remain free flowing in the system to seal future leaks.

Easy Straightforward Installation
Our patent pending Direct Inject design is the easiest and fastest leak sealant installation method in the market. No more messy syringes, fussy pressurized cans, or specialized tools!
