The EPA link I provided does not support your conclusion - what is the source of your information?

Agreed, I did not think it was legal to use Duracool in MVAC systems.

Yup...and an A/C tech I know told me of a number of systems he'd seen it done on. Ran for years w/o issue and blew ice cold air. Not suggesting that one should do the propane thing, just making a point.
What I find interesting is all of the yack that goes on at this forum about it's illegal to do this and illegal to do that, etc., etc. There are countless "blends" or "alternate" refrigerants available and contrary to what the R-12 purists report, they blow ice cold air. If you say they don't, you have never used them. If the EPA was REALLY that concerned about someone mixing Duracool or Freeze-12 or any other alternative refrigerant with R-12, they would not allow these alternative products to be sold on the open market. If you are a purist, use R12. It's good refrigerant. If you want to use an alternative refrigerant, that's your business. People have been doing it for years and how many cars have exploded by them doing so?

It is legal to use HC refrigerants in a factory 134a system, after evacuation. Mixing is now allowed. It is legal to use HC refrigerants in a converted 134a system, as long as the system wasn't converted for the purpose of moving from R12 to HC. Then it isn't legal. |

I don't know of any cars (first or second hand) that have ever suffered a hydrocarbon based refrigerant fire/meltdown while the A/C was in operation. I'd be a lot more concerned about having an A/C condenser full of propane sitting right behind my bumper if I was in an accident. The condensers in a modern cars are paper thin and in virtually every moderate to severe front end collision the A/C condenser will end up getting punctured. If there is an ignition source while your Duracool is leaking you are going to be involved in a fire, and you can start a pretty good fire with a pound of propane. Also keep in mind this hazard is not yours alone, the passengers in your car and other cars/people that are involved in the accident could also be seriously effected if your car goes up like a roman candle. Is it really worth the risk to save $50 on a refrigerant charge? |

I'm more concerned about the poor AC shops who may not know what mix in in the AC system and try to recycle it and contaminate his whole supply, costing him big bucks.

Production - yeah - no more. Availability - uh...still available. R-12 is out there and not ALL of the alternative/blend refrigerants contain propane as some here go on and on about. Lots of bad misinformation going on here. I'm out of this one. Use what you like to keep cool. Been cooling down lots of cars for many years with blends/alternatives.

Ive used freeze12 in my 420sel and it works really well, but someone told me it can gel and lock up the compressor. my system is down right now after replacing the o rings on the expansion valve and the whole drier. all i got to do is have it vacuumed out and refilled with r12 i bought on ebay.

I have been using duracool for 5 yrs or more and it works great and so does the stop leak. I was gonna replace the evaporator on my 96 S600 and the duracool stop leak fixed it. It ran 2 years until I got rid of it..
