Refrigerant Type: r-12
Country of Origin: United States
The original r-12 system was recharged by the dealer (not by me) 3 years ago. I noticed the dealer replaced the original valves with a push and click type that appear to be compatible with the 134-a system. Someone told me this was required by law.
Question: Does this mean they converted the system to a 134-a since the valves were changed or could it still be an r-12? I have a 134-a gauge but it still doesn't fit the valve fittings they put on. Confused.....I called the dealer to find out what they did but they haven't returned my call with the information I needed yet.
It might be another R-12 substitute. These are almost never used nowadays but the EPA had approved several substitutes and they all had different incompatible fittings.
It is perfectly legal to keep using R-12 and keep the original stock threaded fittings.
So if the fittings have been changed, it's almost certain that whatever may be in there now is not R-12.
