The guy at the shop showed me a little canister of Duracool 12a but i told him i would be back so i can talk to you guys first but of course i didn't mention "you guys" HAHAHAHAHA yea so its 50$ for one of the small cans. will i need 1 can or 2 of em? and the tube thing that he has to pump it in says 134a on it. will any left over 134a on that presure tube thing get into my system? and will 1 can be enough?

well, I would have him draw a vaccum on it first and make sure your $50 can of refridgerant won't go bye-bye in a week.

Secondly, you'll have to either find a shop with an R-12 machine so they can draw a vaccum....or buy the conversion nipples and then this guy can draw a vaccum.

Third, no, no 134 gas will get in oyur system fom his manifold.....unless this guy doesn't charge properly and leaves his manifold full of gas.

well can he use a 134 machine to pump in the duracool 12a into my r12 ac?

NM what is a conversion nipple?

classicauto

iTrader: (3)

no, the can should do all the work....does it not have fittings with it?

supra rx-7

he has this tube thing and it has the guage in the middle that has numbers on it like a speedometer and on it it says 134 =/ and the tube thing went to where the ac gas would go into

supra rx-7

so before anything i should mention vaccuming to him before he puts my duracool in? this way it'll seem like i know what should go on so he cant scam me?

Yeah, if he didn't even vaccum it to see if it holds, then he's probably just rying to sell you a can. I do A/C at the shop and I would never try to pull that ****...its too hard on the enviroment.

Anyways, I would definetly tell him to pull a deep vaccum and see if it holds it for at least 20-30 minutes. If it drops much more than an inch or two in that time, you've got a leak and you're new gas will be part of the large hole in the ozone in a matter of days or weeks.

If it holds vaccum, then by all means, charge that mother up!

May hydrocarbon refrigerants be used to replace CFC-12, commonly referred to as "Freon® ," in cars?
No. It is illegal to use hydrocarbon refrigerants like HC-12a® and DURACOOL 12a® as substitutes for CFC-12 in automobile or truck air conditioning under any circumstances.

Duracool is not legal for use in the USA. Might be in Canada, but if the US EPA has banned its use, I don't know how much I would trust it in my car.

Here is the list of approved automotive replacement refrigerants. Freeze12 is on that list:

still guessing, will the freeze12 be colder than 134 though?

RotaryEvolution

yes, and cheaper than what the guy is charging you for the 12a crap, $50CAD per can? sheesh..

supra rx-7

i pulled out 20 and he accepted it but im not gonna use it anymore and now im gonna go get some freeze12 will 1 be enough or 2?

RotaryEvolution

3 cans is what a full system would need, the system technically only needs 2 full cans and a small part of the third but you might be able to get away with just 2 if you pull the system into a vacuum first.

supra rx-7

I looked almost everywhere for freeze12 but no one has it wtf man only duracool so what do i do?? should i just go with the duracool12 or wait for the freeze12 which will take who knows how long before i can get my hands on it?

Hey hey hey hey! Not so fast!!!!

I have 6 cans of the stuff. Actually the envirosafe 12a. Same exact thing except the envirosave smells like pine trees.

I think it is a can of garbage, but I will sell you all 6 cans for $75, shipped.

OK SO do you guys recommend freeze12 or 134a convertion?

classicauto

iTrader: (3)

IMHO do the conversion.

You'll need to get the conversion fittings anyways in order to vaccum the system, then a new airdryer and conversion oil and you're good to go.

But the freeze 12 may be....will be.....cheaper.

supra rx-7

and colder?? is it? and still safe for the car like it wont explode or slowly melt down from flames?

For the record, you guys are in Canada, 134A is probably up to the task. you will have better support from a\c shops. BTW, many of the proponants of teh HC refrigerants are up north too. They will do the job until the outside condtions are extreme, upper 90's and high humidity. You might have a few days of global warming induced heat nowdays where the temp gets to 30C.

I thought you guys up there kept cool from the beating wings of the humongous mosquitos?

supra rx-7

is freeze12 propane?

Icemark

no, as mentioned several times in numerous threads here, Freeze 12 is R134 modified with semi-snythetic oil, instead of a full synthetic that normal R134 has (and what makes it not compatible with R12 systems).
