HCPRO HCLEAK12R Pro Leak Sealer with 45° Swivel Adapter for Easy Access Application 12 Applications 0.25 FL Oz. for AC, Refrigeration, and Automotive Systems Compatible with All Refrigerants.

Seams to do the work. My AC wasn't working properly for a long time. This Seams to fix the problem.

Met my expectations

Try it and it works very good

I injected this to my car’s ac system. After a few weeks all the refrigerant disappeared. I tried this on 2 cars. One car didnt even have a leak. Why is this?

If you are regularly working on AC systems then this is an excellent little product to have. Sometimes its just not worth it to disassemble an AC system for repair. If the leak is very small there is a great chance this product will work for you. If its a really large leak then unfortunately no magic fluids will work. This is a 123 pack and im very happy with the performance.

The Angry Mechanic sez,I am not typically a "leak saler" type of guy, I believe in fixing things the right way, but I am also realistic and understand some things aren't worth putting a ton of time and money into.I got this stuff to compare to my tried and true red Angel sealer, it looks similar although the syringe injector is different/.This kit includes an adapter (its HIDDEN inside the lower portion of the box) but that adapter is for older style fittings and basically everything I work on has R134A quick connect fittings. However if you were working on an a/c system you could inject some into the lines while it was apart. I have a professional grade tool that I use that can inject directly into a fully charged and pressurized system, you could not do that with these, the pressure would blow the plunger out of the syringe and spray everywhere. The system must be depressurized for these syringes to work.When I used Red angel I would usually put ONE ounce into a car/truck system, meaning I would need to use FOUR of these 0.25 ounce tubes! so it's not really a cost advantage.Nothing in thier instructions tell you how much you should use.One thing I can say from experience, if your condenser is cracked or the front compressor pulley seal is leaking then NO leak sealer will work. If you just have a seeping hose, o-ring, or gasket then some leak sealer might be a good bet.So far I have this installed in 2 vehicles and time will tell if they come back or not. So far I haven't had any negative issues or concerns that would prevent me from using it.I Hope My Review And Pictures Were Helpful To You !!
