Nikolas T.

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

Nathan B.

"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."

Carey C.

"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."
