Anyone tried this refrigerant as a direct replacement for R-12?

Re: R-414B vs R-12 or R-134
Otherwise know as Hotshot, right? Made by ICOR. It is a blend, 50% HCFC-22, 39% HCFC-124, 9.5% HCFC-142b, and 1.5% Isobutane. HCFC-22 requires the use of barrier hoses. I do not have any experence with it. Check out this EPA site: http://www.epa.gov/spdpublc/title6/snap/macssubs.html

Crushed Ice
I've always used crushed ice. Wouldn't all these chemicals affect the taste of the vermouth? (let alone the jalapeno stuffed olive)

Re: R-414B vs R-12 or R-134
I have never heard of R-414B. But be careful if you don't know its make up. I have heard of some so called "drop in" R-12 replacements containing butane and propane. Stick with either R-12 or R134a. In my store I sell both along with a product called AutoFrost. My customers have mixed feelings toward the replacement stuff. One major problem with replacement blends is that the recyling machines will be ruined if put in them, so my shops will not work on cars with replacement R-12. If you convert to R-134a, it has smaller molecules, so if the hoses are not up to snuff, it will leak out. Then you will have to use barrier hoses. Also R-134a runs at higher head temperatures, which may cause a problem on early Corvettes.Comment

Joe,
How does a shop know if a car has R-12, R-134, or some other blend that may screw up their equipment? Is there a Fed regulation that requires an ID tag on the system, or do they have to go on what the customer says?
If a less automotively inclined person bought a car that had been converted, they might not even know what refrigerant is in the system. Seems like it would make the risk unacceptable for shops.

Re: R-414B vs R-12 or R-134
It is called "hotshot" according to the material I have. EPA indicates it is a legal replacement but I would feel more confident purchasing some of it if I knew if anyone else had good results using it.
My 75 has trouble cooling with R-12, and 134 is less efficient plus the conversion costs, so I would like to try the 414.Comment

Re: R-414B vs R-12 or R-134
Chuck, there is a requirement that there be a label about the conversion. Also each type of refrigerant uses its own special types of adapters so that R12 equipment will not fit on 134a fittings, etc. Most shops also test the refrigerant before doing anything. They don't want to get some odd-ball refrigerant mixed into the 30 pound cylinder of R12 and ruin the whole batch.

Re: R-414B vs R-12 or R-134
Tom,
Thanks for your response.
The thought that got me started was how to deal with the problem of a "foreign" conversion label, tag, etc., if you submitted a restored car for judging that had been converted to R-134 or other refrigerant. Probably illegal to not have the label or to remove it, and sure to lose you a few judging points if it's there.
Have you encountered this before?

POA adjustment for 134 conversion?
I read the website on converting, but I cant find any locknut or adjustment bolt on my POA valve (new delco replacement). Anyone else find it?

Re: POA adjustment for 134 conversion?
It should be inside the large hose coupler; the fitting must be disconnected. This implies no freon in system!

John,
If you are having trouble cooling with R12, I would do a lot of system checking before changing from R12. That system is basicly the same one that cooled the full sized Impala. It is a very capable system. But on older Vettes it seems that other problems get in the way of its cooling. One big issue is the seals in the heater box going bad/rotting away and letting engine compartment heat through firewall. Check the system out very carefuly before making any changes.
