A/C Stop Leak | #49496

 Product Description


Red Angel A/C Stop Leak repairs common leak points in automotive A/C systems. Activated at the leak point only, Red Angel will not crystallize with existing oxygen or moisture in the system. After AC leak repair is achieved, Red Angel will continue to lubricate and condition working parts. Use Red Angel to fix AC leaks, for preventative maintenance, or to warranty hard part replacement against future leak points.

  • Remarkable ability to repair and seal AC leaks in condensers, evaporators, connection hoses, gaskets, and O-rings 
  • Contains no solid or particulate matter that will clog the A/C system, or harm a recovery unit 
  • Forms a chemical weld sealing leaks in both R-12 or R-134a systems 
  • Safe to use and best of all — it’s a permanent seal

    I spoke to you about options for keeping the air conditioning system going in a couple of my older vehicles, both of which have slow leaks in their systems. You recommended a relatively new product called "Red Angel A/C Stop Leak". Although a little pricy I decided to try it on my 93 suburban. After having my local A/C shop top up my truck's system with fresh refrigerant I added a can of the Red Angel product and crossed my fingers. I'm happy to say that the product seems to have worked since the A/C system worked flawlessly throughout the summer and fall. In the past, the system would only cool for a month or so and then require more refrigerant to keep on working. Pleased with the apparent success, I ran the same process on my wife's old but trusty (she won't let me get rid of it!) 85 4x4 Toyota wagon in early June with the same results. The A/C system in her car ran just fine throughout the summer-fall cooling season. Thus, I'm very pleased with the product and the excellent results, not to mention the cost savings over the cost of constantly adding refrigerant. At the age of these two vehicles it isn't an option to have the system properly repaired . Thanks much for the excellent advice.
