I am nearing the end of rebuilding my aircon system (evaporator blew) and wondering what gas would be best. >From what I understand:- R12:- + low pressure, less strain on the seals throughout the system. - illegal, flammable. R24 or is it RS24:- + low pressure, less strain on the seals throughout the system. - rots the seals. R134a:- + non-flammable - does not run as cold, runs at higher pressure therefore more likely to find leaks. I have got the above pro's and con's correct. What should I go for?
