halokilller Posted July 30, 2013 Share Posted July 30, 2013 I have a r12 service valve that looks like this but it is stuck in the open position. http://thumbs1.ebaystatic.com/d/l225/m/mw64HfPk78hZ4jZlrpFvWjg.jpg Has anyone been able to find a service valve that threads into the 280zx ac compressor but fits a r134a fitting?

Pharaohabq Posted July 30, 2013 Share Posted July 30, 2013 Haven't looked for one myself, but there's a big difference between R12 and R134a. if you're going to change to the newer type, you'll need to have the whole system purged and cleaned out then compatible lubricant added, then the refridgerant. It would be a good idea to talk to a reputable AC shop. They might have adapters too. Quote Link to comment Share on other sites More sharing options...
