idosubaru Posted May 19, 2010 Share Posted May 19, 2010 Anyway way to know the size or source these without taking them out and into a store to match? How standardized are these? Are all legacy/impreza the same? Are R12 and R134 sytems different in terms of the valves? Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted May 19, 2010 Share Posted May 19, 2010 With these questions, are you trying to convert an R-12 to R-134? If so.... In my experience the Schrader valves are generic to all R-12 systems in all cars, and 134 systems are generic in all cars in their respective systems, but not interchangeable between R-12 and R-134. You see this played out in the converter kits, when switching from R-12 to R-134. One kit fits all in terms of modifying the ports to accept the larger R-134 hose connector.

idosubaru Posted May 19, 2010 Author Share Posted May 19, 2010 Oh sorry I was mainly wanting to know about the valves, sizing those for standard EJ replacements. While I have my friends A/C apart I'd like to install new ones. Be nice to know if they're standard, all legacy/impreza the same, or something like that?

Pretty sure they are all the same amongst Leggies/Impreza. Update.........read on another thread on this forum that there are a variety of sizes. See very recent thread re: 97 OBW A/C issues. Then again, maybe you wrote the original thread. Edited May 19, 2010 by Rooster2 update...with more info Quote Link to comment Share on other sites More sharing options...
idosubaru Posted May 19, 2010 Author Share Posted May 19, 2010 No i didn't see or write that thread, thanks Roost, I'll check it out! Quote Link to comment Share on other sites More sharing options...
