r33 aircon gas

[Mick]

ok so i have done alot of reading on this but im still a little inclear as some say yes and some say no, anyways my aircon hose was melted when i had a screamer pipe on it that was pressing up against it, i dont have the screamer pipe on it anymore and i fitted a replacement hose, so obviously i have no gas in the system at all anymore. I want to get it refilled but im unclear what type of gas to get it filled with, some say its r12 gas that it takes and that they dont use that gas anymore and that i am supposed to have the fittings changed to r134a fittings and that i am supposed to have the compressor modified to take the new type of gas, but then others are saying that it was a scam and that r134a can go straight in it without any modification to the compressor and that i just need to get an adaptor for the fill fitting. At the moment it has the stock pale green cap on the fitting. So my questions are:

 

what gas is supposed to be in it, is it r12?

do they still sell the r12?

is r134a safe to use in it if it was made for r12?

does the r134a rot or seep through r12 seals?

do i have to have the compressor converted from r12 to r134a?

if it was your car what would you do to it?

 

thanks guys

R12 is dead....died with global warming.

R134A is the 'environmentally friendly' alternative, it is not as good cars that were made for R12, but on some later model ones you would be lucky to see a difference.

I haven't heard of 134 affecting seals etc....and yes some fittings have to be changed for 134.

if it was my car I'd take it to an A/C guy [or several businesses] and talk it over with them, his replies and knowledge will help you decide who knows their stuff and who you will trust.
