Remarkable ability to repair and seal leaks in condensers, evaporators, connection hoses, gaskets, and O-rings. Contains no solid or particulate matter that will clog the AC system, or harm a recovery unit. Forms a chemical weld sealing leaks in both R-12 or R-134a systems. Safe to use. It’s a permanent seal. Red Angel AC Stop Leak repairs common leak points in automotive AC 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.
