Freeze 12 isn't based on HC. This is why I use Freeze 12.

Freeze 12 is 80% R134a, and 20% R142b, as listed by the EPA

If you need o rings, the kit autozone sells will have enough to last you a lifetime.

My A/C is now fixed and once again ice cold, and not a minute too soon with the 100*F temps today! Anyway, it would appear that one of the O-rings on the receiver/dryer literally disintegrated itself over the past 22 years; the ring that came out looked more like a rubber skid mark than an O-ring. Put on a new receiver/dryer, and had the shop evacuate the system for about 45 minutes on a deep vacuum. Then I had them check to verify that it could hold vacuum for at least 30 minutes after shutting off the vacuum pump. It did, so I had it charged to spec with R12 and had them add in some UV leak detect dye just incase. With the temps today at about 100*F, my vents were blowing out air at 47~50*F once it was fully charged, not too shabby.

Glad to see you got it squared away. How much was the R-12? Do you still have your arm and/or leg?

Still have all my limbs, but he charged almost $50 per can of R12, and it took two of them (28 oz). Seems to be the market rate. On ebay, R12 runs about $45~50 per can with shipping from the "buy it now" dealers. You can find it cheaper on ebay auctions and might get lucky, but after bidding on a few of them and not winning, I got fed up waiting.
