Compatibility of Rev3 and Rev1 A/C connectors

Post by yokomomr4bx »

Question for anyone in the know. I'm rebuilding the A/C system on my Rev3 and have sourced quite a few of the pipework specific to Rev3 (drier and pipework connecting to the pump). What I'm wondering is whether I can get away with Rev1 pipes that go from front to back, or is there a difference in the connectors used to join pipework together due to the R134a gas used in the Rev3 system?

Hope that makes sense, cheers.

For anyone searching this thread in the future looking for an update... rev1/2 A/C connectors will NOT fit rev3 fittings - at least not at critical areas such as the connection to the compressor or condenser. The fittings are the same rough shape but the bore diameter is completely different. I have no doubt it could be made to work somehow, but it's truly not worth the effort. Find the correct parts.

Bit late but this is probably because rev1 and 2 mostly would be R12 systems and the rev3's are all r134a
