My AC leaks down. It works fine as long as there is stuff in it but it goes away in a thousand miles or so. I know there is some seal condition and 'stop leak' for R12 and 134 etc. Does anyone make something similar for Duracool.
I have access to a freon 'sniffer' to find leaks but that won't help with Duracool.
I guess I could just keep putting Duracool in but I'd rather fix it right.

Why not use dye to find the leak? It worked on my AC. Found that the front seal on the compressor was at fault.
Stop leak products always seem like a last resort to me.

Kerry,
Duracool sells two products:
Duracool® SystemSeal 4 oz. Can
Designed to repair minor leaks in the evaporator, condenser, gaskets, "0" rings, connecting fittings and metal lines. Duracool®
SystemSeal was designed to eliminate costly repairs in the form of replacement parts and expensive service labor. Duracool®
DuraDry may be used safely in all mobile air-conditioning systems. Compatible with (Duracool 12a®, Duracool 22a®, Duracool 502a®,
R-12, R-134a, R-22, and R-502.)
Duracool® SealQuick 4 oz. Can
Every year it was normal practice to replace the lost refrigerant that leaks out over the winter months. This procedure is very
costly and prohibited in many parts of the world today. Leaking systems add to the problem of global warming and ozone depletion.
Many leaks in the automotive air-conditioning system occur at "0" rings and gasket areas. As they age, these materials begin to dry
out and shrink.
Duracool® SealQuick is the economical solution to this problem.
As I understand it these products are liquid that solidify when they come in contact with air, NEITHER of them will work if the seal
at the front of the compressor is leaking.

Just a note of caution; I used a can of Duracool stop leak in my Cherokee and by the next summer, the refrigerant was gone. When I went to recharge it, it would not hold a vacuum. Thinking I was doing something wrong, I added a can of Duracool anyway. It all immediately leaked out the front seal of the compressor. I had a local auto refrigeration guy replace the seal and he said it had turned soft and had swelled up pushing it out. Just what happened to me.

Not positive but I think many of the the ac and engine oil system stop leaks rely on swelling of seals and o rings.
Usually takes a bigger leak to notice it with propane based refrigerants, so you might have to fix it. My Suburban won't hold red tech or dura cool any more. : (
