Air con filling adaptor

[waad_uk]

Hi Guys,

I know this has been asked before, but I need to know what fitting my 93 aby has on the compressor. My system came out of the factory with R134a and not the older R12.

The high side has the standard snap on connector, but the low side has a screw on fitting. Now this fitting is larger than an R12 standard fitting (We already tried that one!).

Anyone know what thread this is, or what type of fitting this is? I dont want to have to go down the route of changing the adaptor as the system still has pressure.

Cheers

Ed

You should run a vacume test for about 15mins, then you will be able to put the correct charge/amount of 134a gas into the port top left of the rad.
Dont forget the oil
