Freeze 12

[sport71]

I did some research on Freeze R12, and it is said to be better than the R134. You don't have to change a thing on your old A/C system. You don't even have to change the oil. It costs like $10-$12 per 12 oz. can. I'll be using the Freeze R12, once I vacume out the system and see if it doesn't have any leaks. So I'll be chilling here pretty soon. Cool huh..

Good evening Ruben!

I looked in to this six or seven years ago with the same findings: R-12 is generally a more effective refrigerant than R-134.

Since R-12 wasn't legal to sell in California at the time, I drove my vehicle to Nevada and had it charged there. I had a trip planned anyways so it worked out well.

Over six years later, it has had zero maintenance. It still blows icy cold air!

EDIT: I just re-read your post, and realize that there could be a difference between R-12 and Freeze R-12; are they two names for the same stuff?

it require that 90 percent of the r 12 still be in the system to use it. it is a top off solution to using the old R12.

Duracool is even better and can be used in either, you can even get the kit at walmart!

Both my trucks came from the factory with the 2/55 system installed. Its maintenance free and has a lifetime warranty.

I still have about 18 #'s of original R-12 if anyone knows of anyone in the market for it. I still need to put in an A/C system at some time in the future but was thinking about upgrading.

R-12 shows up on eBay quite regularly and as far as I know it is not illegal to sell the stuff. A business has to pay a huge fee (tax) in order to package and sell R-12. R-12 does not wear out but gets contaminated in a system.

I researched Freeze 12 a while back and their is a lot of information out there, some contridictory. I understood that Freeze is a direct replacement for R-12. Freeze is a combination of flammable hydrocarbons. If the Freeze system leaks you have a flammable (possibly explosive) situation.

R-134a can be run in place of R-12 with an additive for the mineral oil. It is less efficient and has difference operating characteristics. The government requires different fittings. The R-12 hoses are different than R-134a and will corrode or leak if R-134a is used. The desicant in the dryer is also different. Many have had no problems with directly replacing R-12 with R-134a, no figure.

R-134a itself is scheduled to be replaced in the not to distant future. The auto industry has not agreed on a replacement for R-134a. There are many different working fluids that are being researched.

The name is Freeze 12 not (Freeze R12) and it's a direct replacement for R12. One of my old A/C systems would freeze with the R12, it was the coolest. I hope that the Freeze 12 will work good on the hot days. I know that I'll have to install an electric fan in the front for sure with the extra heat from the A/C radiator.
