A/C Pro Super Seal All-in-One Stop Leak (12 oz)

When the AC starts blowing warm, a refrigerant leak is usually the culprit. A/C Pro Super Seal (ACP108) is an all-in-one product that combines stop leak, R134a refrigerant, red leak detection dye, and an acid buildup remover in a single 12-ounce can. There is no need to chase with separate refrigerant after treatment.

The stop leak formula targets both metal and rubber leak points. It seals metal leaks in evaporators, compressors, and condensers, and seals rubber leaks in O-rings, gaskets, and hoses. The included red dye helps identify larger leaks that may need a more involved repair by showing up under UV light at the leak source. The acid remover protects internal AC components from corrosive buildup that can shorten system life.

Application uses a push-button dispensing mechanism that connects directly to the low-side service port. This product works best on small leaks. For larger failures or a system that has lost all its charge, a proper diagnosis and repair at a shop is the better path. But for minor seepage that is slowly draining your system, this can restore cold air and buy significant time.
