Unique fittings for each different refrigerant. See the section titled "Unique Fittings" in this page of the IMACA study guide: http://www.imaca.org/sg-14.htm

Each new refrigerant must be used with a unique set of fittings to prevent the accidental mixing of different refrigerants.

My interpretation of the regulations was right on. It is obvious I read the regulations. thanks for posting the link

Diesel Jim, If Brian's statement that Freeze12 is 80 percent 134a... then what is the possibility that it simply uses the 134a fittings ?

Rick, that was an excellant link.... I could have copied and pasted much of it instead of composing answers in this thread...

You know the sad part of this whole thread is that I put it up to help people. I am getting alot of hair splitting and bashing because I used Freeze 12.

Read my lips. Yes I would use Freeze 12 again, if you don't like it, don't use it.

I would have used R-12 if I had it, but was not worth waiting for. Bottom line is my A/C is 38 degrees, is yours????

Yep, I am getting 38 degree vent temp and it would be lower if the climate control system weren't regulating it at 38.

I do wish that you wouldn't be given a hard time about this. You went to a lot of trouble to share your pictures etc. with everyone and it is appreciated. I hope I did not come off as critical. I did feel that it would be helpful to point out that the R4 is not a good candidate for rebuild, but sometimes you can get a good rebuilt unit.

I have made my opinion about alternative refrigerants known here on mshop. I will not use them for a multitude of reasons, but my goal is not to get in your business if you choose to use them. My goal is for everyone to understand the pros and cons involved. I also like to ensure that people know the law on such things. If they know the law and still choose to break it, that's totally the individuals choice. I won't call the law on anyone.

Good job on the writeup,

I was not really speaking to you Larry. I am going to try and get the vent temps to around 36 degrees. No not by more freon but with a few tricks that I MAY share if it works. However, given the bashing I got I may just keep future mods to myself.

Well I gotta go work on a Dodge automatic.

diesel giant, I think 38 would be about as low as you could go before freezing your evaporator. I can't remember what my second cousin said about the relation to evap temp and vent temps. I would say 38 is a good mark to stick with.

Thanks
David

Share them with us...we love your writeup if not your choice of refrgerants.

Diesel Giant, I was quite interested in all of your writeups...I think I need all of them....

You keep linking to mbz.org for parts, why not here at the Shop where you are posting?

Also, you linked there to get the vacuum valve lever but I can't find that part anywhere on the website...am I missing something?

Thanks for taking the time to document all of the work you did.

I agree with you. If the Freeze-12 is doing the job, why argue with success.

Oh, and BTW, for all his talk, ask Greg what his vent temperature is on the 240D.

I am not an expert but I would guess not. Since the purpose of the regulation is to facilitate easier refrigerant recycling you would want to keep 134a out of a system as pure as possible. The other 20% would have to be gotten out by a distilling or chemical process to get pure 134a. However you could recycle freeze-12 that is kept in only freeze-12 container and get freeze-12 by just removing oil and not refrigerant items.

Sometimes I am not anal enough but I am much more of a pragmatist. Not an anarchist. Unfortunately we had someone butt in here and I got a little ticked at him. Apologies to the rest of the posters. I should have been a lawyer except I can't stand the B.S.

The purpose for each individual refrigerant using unique fittings is an attempt to prevent contaminating recovered refrigerant. This is not usually a problem for the DIYer because they usually simply violate the law and vent it. It is a HUGE problem for those of us with recovery machines because if refrigerant is contaminated, we not only lose the refrigerant but have to pay big bucks to have it disposed of.

On the 124 car the automatic climate control system regulates the vent temp to keep it no lower than 38 degrees. Unless you do something on the sensor and control side of things you will not get it below 38. As pointed out by a previous poster, taking it below this mark runs a high risk of freezing the evaporator anyway.

Good luck,

Larry said it much better than I could but he is correct. This is the reason why I said you only have to worry about the feds if you contaminate someone elses refrigerant because you took it there without the appropriate fittings and warnings and they mixed it with other refrigerant. You can seperate refrigerants but it is different equipment. It also said that somewhere in the 609 study guide.
