Bars Leak AC Stop Leak with UV Dye Leak Detector

Part No. AC-1 Warranty  

Fit of this part varies by vehicle & equipment specs Type of Fit

Bar's Leaks Professional DiFM A/C Stop Leak and Sealer will seal most minor air conditioning leaks. The product works on the principle of the venturi effect and flow, meaning when there is a small leak in the system, refrigerant and some of the stop leak material escape at an accelerated speed. As the liquids escape the pressure below that point actually drops and the stop leak coagulates and forms a no hardening, flexible seal at the leak site. This happens because the vapor density of the stop leak is over 2 times that of the refrigerant. Since the repair stays flexible it can expand and contract with temperature changes. Its non-clogging formula contains no particles, solids or polymers which can plug up the orifice tube and other parts of the air conditioning system. Will not clog A/C recovery/reclamation equipment. Product Features: Permanently seals in condenser, evaporator, hose connection and O-rings & gaskets., Acts as an excellent lubricant for all moving parts inside their conditioning system, Not activated by air or moisture, Contains A/C system UV dye leak detector

Product Features:
  • Permanently seals in condenser, evaporator, hose connection and O-rings & gaskets.

          Comments about Bars Leak AC Stop Leak with UV Dye Leak Detector:

          I bought the Air Conditioning leak sealer with UV dye hoping against hope it would fix my gasket leak on a GM HD6 compressor valve plate.
          And it did!

          I noticed one thing is that the goo sticks to the bottom of the bottle must be stirred up using nail or shaken with steel nuts (like spray can), then I poured into the suction line. Make sure ALL the goo gets into the suction line. I opened system to pour it in near the drier. Since the refrigerant had leaked out, no big deal.

          Ran car for 45 minutes. Leak was gone.
          The leak was big enough that a 29 inch vacuum would drop to 25 in about 4 hours, which is a big leak.

          It is a more difficult way of installing the sealer having to open the system. So many people wont know how to install it even though it is easy enough.
          And if it did not work for some it can be that people did not make sure to get all the contents into the system. Also this will work with all refrigerants such as propane, butane, R12, R134a, R22. So you could use it in your home HVAC if you had a leaky evaporator and save significant money.

          Comments about Bars Leak AC Stop Leak with UV Dye Leak Detector:

          Wanted to compare this one to other liquids types already on market. I personally like Stop Leak Plus and have used for years, but decided to buy this one at local store to see if cheaper product was as good. The oils were on top and the solids were hardened at bottom and they would not mix, no matter how much you stir or shake. I later discovered this company used silica type solids, something that would ruin a compressor and have a hard time sealing a leak. Stay away from this one!

                Comments about Bars Leak AC Stop Leak with UV Dye Leak Detector:

                I have been in the auto repair business for over 40 years and was always hoping that someone would perfect a liquid stop leak for automobile a/c When I opened the first bottle all of the ingredient was settled and stuck in the bottom of the bottle the remainder of the bottle is pag oil with dye. I opened another bottle same thing I tried to remix the solution no success. I returned the product for a refund This may be a good product if Bars can come up with a way to keep the solution suspended and from settling to the bottom of the bottle. Bars has been around a long long time and I have the utmost confidence in their products but I think this one needs a little more development.

                  Good product, works well. Must have an A/C Recovery Machine to use properly. Not for the diy mechanic.

                      Product is in liquid form, in wide mouth plasic bottle; with no way to install in A/C system using commonly available recharge kits. Consumers wishing to add A/C sealer should buy freon with sealer in it.

                      I wasted my money.

                          Per the MFR instructions, you install it using an oil injector thru the A/C low port.

                          I do not believe that this would fix a hole for you. Usually, products like these are made to fix the leaks in seals.
