The finest hydrocarbon refrigerant available!....
My Rams ac was not acceptable on R134a, but became GREAT on HC290....ICE COLD

Re: Enviro-safe R12........
That's a fine looking 84Z there.
I've read in Europe they use propane all over to replace R12. Wondered about this myself since R134 in a third gen leaves a lot to be desired on a hot summer day.

r134 is only flamable when under pressure mixed with air...and even then its not that volatile.

Re: Enviro-safe R12........
I beg to differ.....R134a mixed with refrigerant/pag oil in a fine mist is extremly flammable, explosive even. You can light the fog right up, don't believe me.....TRY IT!!!

I put this in my s/10 and it works better than the stock stuff

Re: Enviro-safe R12........
This looks like a really good alternative, just, how legal is it to put it in your car?
http://www.epa.gov/Ozone/snap/refrigerants/hc-12a.html
It looks like ES-12a and HC-12a are basically the same thing, a hydrocarbon mixture of propane and butane.
IMHO, you would need to have a hermetically sealed system to use these hydrocarbon refrigerants. Both propane and butane are heavier than air. This just doesnt seem safe.
Maybe we can get Mythbusters to try to do some tests on an older car like ours and see how dangerous this stuff is.

I have used the envirosafe in mine after I tried 134a. The envirosafe seems to work better. I put it in about 5 years ago and have not had any issues.

Re: Enviro-safe R12........
I also have a 93 truck with a slow leak that I do not drive often. I use the 20lb BBQ tank to top off the AC when I need to use the AC in the truck. I have not had any issues with using normal propane...yet.

Re: Enviro-safe R12........
I have been using enviro safe es-12 for quite a few years in r-12 and 134a vehicles.It works great,better than 134a but not as good as r-12 in traffic when idling.The issue of being flammable is way over stated.I was removing a compressor hose from a system that still had some es-12 and due to my wrench hitting the starter lug,a spark caused the es-12 to burn.No explosion,only a small weak flame easily put out with no damage to the vehicle.
It runs with less head pressure and the molecules are said to larger than 134a,so not as prone to leak.Works with all oils also.
Only problem is it is not sold at any of the auto parts chains.Only available on line.I buy several cases at a time and that carries me through the summer season.A good,inexpensive product.

Re: Enviro-safe R12........
I brazed a fitting that fit the A/C manifold hose onto a old fitting for the 20lb propane cylinder.

Re: Enviro-safe R12........
The AC compressor started just cycling and not cooling on my '92 so I figured I'd top off instead of convert. Enviro-safe recommended 40 PSI but I accidently went to 45 PSI. It's cooling ok enough for me but should I drop the pressure down to 40 as suggested? Do I do that with the AC on and just leave the can off the hose/gauge?
