HC-12A OWNZ YOU
i converted over to r134a and my air was only blowing at 60* at the vent, switched over to this new stuff called DURACOOL 12a, the a/c blows at 29* can you say holy cold nuts!

Hate to burst your bubble but do you realize that the HC stands for hydrocarbons, they are highly flamable. Don't ever wreck your car or else your fucked like a roasted marshmellow.

CFC-R134a and HCH-r12 (I think thats correct) aren't flammable by themselves except for under really high pressures, but one of the reasons you aren't supposed to contaminate them is because than the H and the C combines to make HC which becomes flammable. Other things like Propane make good refrigerants however they are of course flammable. I would stay away from anything other than the mainstream R12 and R134a.
I spend 8 hours every Friday learning about A/C for school. At least some of it I can remember.

Re: HC-12A OWNZ YOU (FourthGenHatch)
it says in the manual at 4.7% in the air its flammable at 1680degrees at 10% 1600 degrees, it says in the manual the chances of the HC catching on fire in case of an accident is 3 in 10 MILLION and the fact that it only takes 15 Ounces to fill the whole system i wasnt too worried

Yea those don't mix for sure they have different types of hose you will need to change oil Ester etc drain the system vacuum etc properly..
Its not that hot in ca right now when its 110 your ac system **MIGHT NOT** work ur temp in the vent depends on the ambient temp outside.
most ac systems work on 60-70degrees weather but on a hot day when u turn it on won't work

Refrigerant Recovery and Recycling Online Review and Quiz
Online Review Materials (Page Three)
A Word About Alternative Refrigerants
Important: The sale of any size container of ozone-depleting refrigerant, including refrigerant blends, is restricted to technicians who have been properly trained and certified. As the time this information was posted, there was no sales restriction on R-134a, however, this is subject to change. Consult the EPA Information Resources listed in this booklet for the current status on sales restrictions.
Refrigerant producers and the motor vehicle manufacturers conducted exhaustive research on alternative refrigerants to R-12 and finally chose R-134a because of its safety, performance and non-ozone-depleting characteristics. By the 1994 model year, all vehicle manufacturers had made the switch to R-134a as the original equipment refrigerant.
It is also possible to change older R-12 systems over to R-134a, a process known as a retrofit or conversion. Although requirements vary depending on the year, make, and model of the vehicle, this procedure usually includes changing certain system components, as well the addition of R-134a compatible refrigerant oil prior to charging with R-134a. For best results, check with the vehicle manufacturer for specific retrofit guidelines and the availability of retrofit kits. Retrofit kits and information are also available from various aftermarket sources. General retrofit guidelines are also available from the EPA. Order "Keeping Your Customer's Car Cool: Some Guidance On Retrofitting A/C Systems To R-134a" from the EPA Hotline, or from the EPA website as listed under "EPA Information Resources". One important note: Prior to charging with R-134a, all R-12 must be removed. R-12 and R-134a must never be mixed.
The world of alternative refrigerants is changing rapidly, so it's wise to keep a close eye on industry journals for news of other alternatives that may be listed as acceptable, under certain use conditions, by the EPA as per its Significant New Alternatives Policy (SNAP). Although R-134a remains as the only OEM-recommended refrigerant for retrofitting, the EPA developed the following chart to list other alternative refrigerants. (The information on this chart is current as of June 3, 1997; updated copies can be obtained by calling the Ozone Protection Hotline, or visiting the EPA website). This chart not only lists the refrigerant names, but also contains other important information regarding the status of acceptability or unacceptability. Only the refrigerants listed with "ASU" in the status column may be legally installed in a mobile A/C system. It is also important to note that the "ASU" designation does not indicate the performance level of these refrigerants in any given A/C system. Additional refrigerants may be listed as acceptable in the future. Also note that some refrigerants are listed as unacceptable due to flammability, or the fact that they contain CFC-12. These refrigerants are OZ-12, HC-12a, R-176, Duracool 12a, and R-405A.
As this booklet went to press, the EPA is aware that the following states and localities prohibit the use of flammable refrigerants in automotive air conditioners: Arkansas, Arizona, Connecticut, Florida, Idaho, Indiana, Kansas, Louisiana, Maryland, North Dakota, Oklahoma, Texas, Utah, Virginia, Washington, and the District of Columbia.
USE CONDITIONS
Under the SNAP rule, each alternative refrigerant must be used in accordance with the conditions listed below. If you choose to use an alternative refrigerant, make sure that you pay strict attention to these conditions. In addition, be sure that the shop has dedicated recovery and/or recycling equipment for that refrigerant.

Re: (stk crx)
ya im using duracool 12a, it also said HC12a, i dont give a damn if its flammble at 1600 degrees, there is only 15 ounces of it in my car and its so damn cold i have to TURN OFF my a/c

Re: (importboi22)
I am considering using the Duracool 12 in my 89 hatchback, I read about how unlikely it is to catch flame in an accident. My worry is what if the evaporator springs a small leak and someone is in my passenger seat smoking a cigarette? Are they going to get torched?

You mean unlike the stuff inside of a specialized tank inside the car design to protect it from damage in case of an impact? Oh yeah that stuff. Gasoline does not burn in large quantities. Go throw a match in a barrel of gas, it's not going to light. You mean unlike the stuff inside of a specialized tank inside the car design to protect it from damage in case of an impact?

A/C lines are not strong enough to resist puncture and there is enough oxygen:refrigerant ratio so it would burn.

I highly disagree with this. Fill your garbage can with gasoline stand in it and light a match, then come back and tell me what happens.

There should be no oxygen in the A/C lines just as with your gas tank. Also, gasoline ignites at a MUCH lower temperture than the Duracool hydrocarbons.

Just out of curiousity, where did you find this stuff? I've looked on ebay but just find cases or 30 lb tanks of it. I'm thinking about selling the r12 I just got and snagging some of this stuff up.

Let me start by saying I'm NOT a chemical engineer. But the gist of this IS true.
Gasoline itself doesn't burn. It's THE VAPOR that is flammable. If gasoline itself burned we wouldn't need complex fuel systems. And an over-fueled car would start w/o a problem. After saying that, though. I wouldn't try the above.

This is all true, I was just trying to point out that oxygen is not mixed in with the Duracool just waiting to ignite.
