Can you use stop leak to help stop a small leak in a c compressor?

I wouldn't recommend. Pressure on low side is still very high and ac system has a radiator just like a car, it will gum up inside everything and probably not stop leak. You should replace the hose or repair the leaking connection. If its a pinhole in metal or compressor case, maybe can be tig welded or something if it's not a part that can be removed
