DURACOOL FREON REPLACEMENT

As previously posted numerous times, most cheap non-freon replaxcements contain PROPANE and many are illegal to use in some states. Check the list of ingredients, then check with your local AC experts to see if your area even allows the stuff. Lots of gasses produce a refrigeration effect; few are legal or desirable in mobile units. Carbon disulfide is used in commercial refrigerator systems for instance, but in the event of a wreck, you'd be hard pressed to stay within 50 fert of the car... unless you're really fond of rotten eggs.

Jeez, sorry I asked, but in the numerous posts I have seen and the search I did before I asked the question, I have never seen an answer to that specific question, I saw one guy make a reference to it which is how I heard about it. I looked at their website and it does contain methyl propane, but their salespitch says we drive around with 30 gallons of high octane gas (I have seen numerous posts from some of the owners looking for aviation fuel) and many P car owners have nitrous tanks installed, probably also dangerous in a collision. Their website has the following quote, "The Auto Ignite rating for HFC-R134a is 1328(F) Degrees. The Auto Ignite rating for Duracool 12a is higher at 1635(F) degrees."
Not being a chemical engineer, I was trying to determine if any of their claims had merit.

Gary;

I recently received my EPA certification for mobile A/C refrigerant. As stated by the EPA the following are ACCEPTABLE substitutes(Subject to use conditions):

HFC-134A (R-134A)
FRIGC (FR-12)
FREEZONE (RB-276)
IKON-12
FREEZE-12

ACCEPTABLE substitutes (But hoses must be Barrier type hoses):

GHG/McCool/AutoFrost-X3/R-406A
GHG-X4/McCool Chill-It/AutoFrost-X4/R-414A
Hot Shot/Kar Kool/R-414B
GHG-HP
GHG-X5

Any Flammable substitue for CFC-12 is UNACCEPTABLE and ILLEGAL to use in the U.S.A. in mobile A/C systems.

The following are UNACCEPTABLE substitutes:

OZ-12 (Due to flammability)
HC-12A (Due to flammability)
DuraCool 12A (Due to flammability)
R-176 (Due to composition)
R-405A (Due to composition)

Hope this helps.

Mark, are you using a rotary pump? Is the unit under the dash stock?
