Amazon.com: Freeze-12 Refrigerant R12 AC Replacement 12oz. Cans: Automotive
Need to recharge my a/c system, looking for a suitable solution, any ideas?
You can still buy R12 , BUT not for mobile use. Total BS system.I believe the change was only due to Duponts patent running out on R12. Therefore due to extensive lobbying in D.C. R12 was banned and R134a became the replacement.
What he says.I'm running Freeze 12 in two FJ60's and have used it in all my R-12 vehicles.
It is non-flamable ( no propane ) and works as well as R-12 in the Az heat.
I've been using it well over ten years with no failures or complaints
material data safety sheet:
Remember R12 and Freeze 12 are NOT the same thing.
The way a shop explained it to me was "We use Freeze 12 in a vehicle that will be scrapped soon because once it has Freeze 12 we won't touch it again."
I'd recharge with R12 if the system had it and I felt so inclined but I'd NEVER use Freeze 12 because of the uncertainty of future servicing. Even my FJ55 is running R134a.
My comments are not related to how well it works but rather to the serviceability of the system once you charge it with Freeze 12. If you're OK with that then use it, if not then do what is necessary to keep the truck serviceable as far as the A/C system is concerned. My FJ55 and the BJ60 are both using the OEM systems with R134a and they both cool adequately, even in AZ.My 86 ford F350 has been running it 15 years now and my FJ60 , 10 years. Your right, someday they'll be scrapped, but not because of the the AC not working.
You'll find shops that swear by it and other just to afraid to try.
One thing I know is that it's much cheaper to go Freeze 12 than replace a R-12
system with 134. In a place like AZ an R134 retrofit usually requires a larger condenser and operate at much higher pressures putting more load on all the components. Freeze 12 requires nothing more than an evacuation of the R-12
and even works with the same lubricants as the R-12 system. The Freeze 12
will cool as well as R-12 without system mods where a R134 won't come close without replacing components
I'm tempted to try F12, but I've still got four 10oz cans of DuPont R12 in my garage. I just need to get my hands on equipment to evacuate and recharge my system (wanna use the stuff that's still in there, and just top off if needed from a 10oz can).
Bitch of it is finding the equipment is almost as hard as finding the actual R12 in small quantities anymore.
