ptt Posted April 24, 2017 Share Posted April 24, 2017 (edited) I have cracked AC aluminum tubing where it comes off the compressor itself and the hoses start to go to the accumulator thus losing all the r134a refridgerant. I have acquired everything to fix the problem. The system worked fine for a couple of Summer seasons and had been converted to r134a by the previous owner. I'm wondering what high and low pressures I should look for when I recharge the system. Ive heard that the r134a conversion in the Reatta AC system only requires approximately 80% of the original R-12 pressures. Like possibly HIGH side 180 and LOW side 40 maybe??? I'm considering using ENVIROSAFE-12 which requires even lower system pressures which would put even less strain pressurewise on the system.

harry yarnell Posted April 24, 2017 Share Posted April 24, 2017 What are these pressures you quote? Static? They don't look like suction or pressure numbers... Link to comment Share on other sites More sharing options...
