Leak Saver Direct Inject AC Leak Sealer Small System | AC Stop Leak for Most HVAC Systems Up to 1 Ton | Works with All Systems & AC Refrigerants | Made in the USA

Great find; had a small leak in a DIY mini-split system. Goodbye leak.

Super easy to use and well-packaged.

En mi opinión creo que es más propaganda que lo que en realidad hace, yo lo use y no me solucionó el problema tal vez a alguien más si,pero en mi caso yo le doy una estrella

Its an awesome product works amazing

I love this product! Instead of an expensive unit replacement for a refrigerant leak, Leak Stop saved the day. Even after a week of scorching 90-degree weather, my AC is still working perfectly. Applying it was a breeze, especially with the convenient CO2 applicator. Highly recommend for saving money and hassle-free maintenance!

if you have a small ac leak you can slow it down or fix it until you can get something better. you will need a hose to add freon gas to whatever you are working on , R-22,R-410a, R-134a or whatever does not matter, you can mix freon, just add a little at a time the gases expand at different rates, to much no good. get the hose, get the freon gas, you may need an ADAPTOR to screw this sealer injection shot onto the input port on the ac unit you are attempting to seal, first you should try putting a little freon into the system if you hear it just blow right out ,you should try to close the hole ,solder or band clamp with rubber this is only effective on smaller than a pinhole ,works good, if I have a unit that leaks down after 6 months it will pretty much fix it, I keep 2 in my ac repair box always, as always I recommend watching a DYI video before you use this , Enjoy

Works great for fridges

Update : After posting my review the seller reach out and offered a full refund. They did not ask me to change my review, but I think it’s only fair that I give them credit since they were not obligated to refund any of my purchase price. The only thing they asked was that I give them another chance in the future, which I may do. Product didn’t work in my case, I followed the mfg. instructions but this did not fix the leak in my mini-split A/C system. Not sure if it’s just this specific product or all product like this one in general, but it was a total waste of time and money. Be aware, there are no refunds on consumable products, so you are going to have to accept the risk if you decide to use this product.

My window AC has a micro leak... I can say it is very minimal leak, it slowly loses pressure for about 3 months but still not totally empty and can still cool to a minimal level. From 65psi, it goes to about 30psi in ~2 months and about 20 psi in 3-6 months. It will not empty out totally and will just stay at about 20psi. So, let us see how this works out for me. After 1 month i will check the pressure again, I know i will lose a little pressure every time I measured with my manifold and will consider this too. UPDATE: After about 20days of usage, the pressure dropped again at 20psi. meaning it was not able to hold the pressure and seal the leak. anyway i enjoyed using it and hope it can work for others

Le produit fonctionne très bien presque toujours…

Fixed leak

It got to me almost empty. It was leaking inside the package. Couldn’t use it.
