What is CA storage? The amounts I posted were the price range for a 30# can of R-12. R-12 (sales by the pound at $80.00 to #100.00)is used in refrigeration..I know...I know it is/was in autos...but actually you have refrigeration systems in autos because of the lower evap temps needed to cool. The replacements are numerous, but #1 is R-134a (not quite as effective, but close). R-22 is for air conditioning is A/C systems...yes years ago R-12 was used in A/C systems until they figured it all out...and then you Carrier who made their own combination of R-500 or called Carrine 500, which was a blend of R-22 and R-12
Enough schooling........

Guys, its time to move, the bottle weighs 30 pounds in the box. If interested, please make an offer and have a current license to purchase R12.

Works perfect.

I have converted many R-12 systems to R134A with no ill effects to the system or the performance. The biggest mistake I see being made is overcharging the R134A system. The converted system requires less than the R-12 system. My R134A conversions cool better than the original because I use less freon.

Al Gore wants to buy all the old R-12 to save the ozone layer.

You need a MACS license (a test is involved as well as a card being issued) to purchase, service and distribute R-12. We use it all the time in many of the older private/corporate jets and the systems are still serviced on a regular basis throughout the aviation world. Last 30# I bought was $1230.00
All you can buy if licensed (legally) is recovered and re-manufactured, but it is still available at many HVAC wholesalers. There have been allegations that the French are still making the stuff and selling it on the black market- there have been several busts on the stuff coming into port in the state of FL in disguised containers.
