Yes. I had Red Angel AC Stop Leak added to my 1993 Toyota 4x4 back in June 2014 and is still operating ice cold . My dealer diagnosed the leak to be behind the dash with either the O-rings in the connections or the evaporator. The cost for repair was estimated at over $1200. I definitely recommend Red Angel A/C Stop Leak (49496) if your AC meets the leak requirements listed: If your vehicle can hold 5 inches of vacuum for 25 minutes or 15 inches of vacuum for 5 minutes. This product is not recommended for systems that lose more than 1 pound of Freon per day or leaking compressors.

Is it possible this is compatible with enviro safe refrigerants? (A 134a replacement/ runs much colder)

Late to answer but yes this will work with r134a drop in replacements. I’ve used it with two different hydrocarbon based r134a replacements, like envirosafe and frosty cool.

Can it be on refrigerators?

YES, BUT ONLY A SMALL AMOUNT AS THE REFRIGERANT CAPACITY IS SMALL. DON'T EXPECT MIRACLES
