## Customer Reviews

### ⭐⭐⭐⭐⭐ Good seal for a/c inverter.
*by E***O on July 10, 2025*

After i put this seal to a/c inverter 2 months ago is work good no more leak.

### ⭐⭐⭐ easy to install.
*by M***R on September 16, 2025*

still under test I installed solution in my system which was really easy to do. then added 410 gass. Its been a week and ductless ac seem to be cooling normal so far.

### ⭐⭐⭐⭐⭐ It worked for me.
*by T***S on August 17, 2025*

I was able to use it on the home AC to stop a small leak without having to redo the copper piping. Once you lower the pressure in the system then you are able to get the entire leak stop fluid inside with ease, Once you recharge and you run the system it will find the small leaks and stop them, you just can't expect it to perform any miracles on major leaks. Easy to use and saves you a lot of headaches on small minor leaks. It is a great value for the money if you can get it to work on your leak. So far so great no loss of pressure in the system after a couple of months. It is very hot now in Florida so a working AC system is a requirement to support the hot summers.
