Default R12

Has any member purchased R12 on the internet or locally? I see it on eBay but is it the real refrigerant required for the older ac systems?

Some of that stuff advertised as R12 is actually not real R12. It is a R12 substitute which may or may not be compatible with actual R12. Shop wisely. Ask questions before buying. The higher priced cans are more than likely the real stuff.

That's why I posted this question. Some or most of refrigerant on eBay states R12 compatible. I've read that to purchase R12 one needs a license. Need more info. Googled
Dichlorodifluoromethane Is R12 freon. Thanks.

You can easily get a license on line. I got mine from the Mobile Air Conditioning Society (MACS). All my cars are now R134, but I used to get R12 from my local NAPA store. Couple years ago it was $50 a can.

So is R12 required? I have converted R12 cars to R134 in the past, but not a 'Vette. Mine is '74.

I got the licence and purchased from Ebay and they never asked for license number. Anyone can purchase just make sure can is sealed and buy can that were manufactured by reputable manufactures

I'd suggest switching over to the R134. You can walk into any Walmart and get it right off the shelf in the auto section. Cheap, too. I picked up 6 cans at the end of last summer and it was marked at $6.00 a can.

Just bought a can of R12 on ebay and I have the recharge kit (hose and fittings) in case I have to give my 79 a shot. The A/C is working good and seems to have enough freon, but it doesn't feel real cold, not compared to today's standard anyway. I remember adding freon from the can back in the day. I took it by an A/C shop and they told me there's not really anything they could do with an old R12 system other than to convert it out and if it was working I should just leave it alone. The car has 25,000 miles and I recently purchased if from the 2nd owner who had it for 30 years up in Michigan and rarely drove it (evidence from the mileage). So I don't know if the A/C has ever been recharged. Should I have the pressure checked before I attempt giving it a fresh shot of freon?

Yes... check the pressures which are based on the ambient temperature.... overcharging is not a good thing and can create same symptoms of undercharged system along with locking up compressor. It's best to have the hoses pressurized/purged with refrigerant prior to connection so as not to introduce moisture/air into the system though empty hoses.
