I wanted to use these to fill my R12 connections with R134 A refrigerant... but from what I can tell these are meant to take an R134 A back to an R12?

The quick connects are meant to threqd on to an r12 manifold gauge that will connect to r134a ports. If your vehicle is original r12, you will have to get r134a adapter ports that thread onto the r12 ports to use these quick connects. Then , once the system is charged , you can either remove them and put the r12 caps back on but you are supposed to leave them in place (with the r134a sticker) to show your system has r134a and is in compliance for inspection. The 1/2" acme thread x 1/4" SAE adapter is to use an r134a can tap and to connect it to an r12 manifold gauge yellow charge / vacuum hose. Of course , the quick connects will thread onto the high (red) side hose and the low(blue) side. The adapters will only fit on the correct port, and the quick connects will only fit on the correct adapter. It is foolproof so mistakes are eliminated. Hope this helps

It works for R134a systems. Not sure when things changed from R12, but it worked on my 1997 Honda.

Not sure what you mean wrong side. I used mine on an A/C Manifold guage set for R22. The blue connector has got to go to the low side, and the red connector to the high side. If your guages are not colored, the low side is on the left. You will notice that the blue connector will only fit on the low side of an R134a system. The low side guage will have -30, which you watch when vacuuming down, to check for leaks before recharging. I am not familiar with other type of guages, so take what you have to an ac place and they will tell you what to do, I finds them pretty helpful. Mine went right on, no problem.

I use them for my residential AC, although the EPA requires you to have a license to handle home AC freon (wink wink). Cars use R134A typically, and I have a different gauge set for that purpose. Also, I highly recommend the SealRight 19100 Yellow Jacket couplers to prevent leaks out, or air getting into your system.

If your car is newer than 1993, your car should be using r134a (or your older pre-1993 vehicle was converted to r134a refrigerant, from R12). This A/C Pro refrigerant is for the newer refrigerant, r134a, i.e. for cars, post 1993. It will not connect to older vehicles using the older R12 freon just by nature of its quick connect/disconnect hose coupling. Use the gauge on the can as a guideline (err on the low side where the green just starts). If you add too much, your car will not cool either. I topped off my Toyota adding a little at a time and checking the inside cooling air with the back of my hands at the interior vents (engine speed rpms should be raised so compressor is engaged). This was not very scientific, but I just wanted a little more cooling effectiveness. Wear eye protection and gloves for safety.

You can really mess up your unit. If your pressures are wrong. But yes these are what you need.

The instructions say all refrigerants. I have used ot for R22, 410A, and 134a without any problems

Yes, this pump is compatible with R12, R13a and R22. However, it will be necessary to purchase an adapter for the pump to fit your manifold line.

Hi, I don't know why I'm being asked and not the manufacturer of this product as I only am a customer myself, however, I could answer your question as no, you can't. They are designed to adapt the original auto HVAC r12 service gage fittings for a car with the R134 type of quick disconnet fittings. You can see the blue and red rings anodized rings on these brass fitstings, those are quick connect sleeves that you pull back to make connection to the newer R134 hi and lo pressure service ports found on 1993 and newer cars. The other end of these fittings you can see is a flair fitting that an older style R12 type hi and low pressure gage set can attach to.

The issue is not brand interchange. The question should be what dimensions does your unit require? This is a good product if your system requires these dimensions, regardless of system manufacturer. I use them in my Trane.

You need these two items. R134A will not work.http://www.amazon.com/gp/product/B00159WZ12/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc;=1Ductless Mini Split System charging vacuum port adapter, Converts new R410a style 5/16 SAE service ports to accept older 1/4 SAE gauge hoses.

It cannot be used with r22 refrigerant. R134a only. Different gauge sets foreach refrigerant.

They are designed to match the tonnage of the unit. The one I bought did not help at all as my Compressor was shorted. It was under warranty, but still cost me $1K to have the new compressor installed, hazardous waste and freon charges etc. You will want to do some searching on how to completely check your system and how this installs before you buy it. I did most of the tests recommended, but did not do all the leads on the compressor, so I bought something that did not help. My HVAC guy told me the kits really don't help a heatpump much? Live and learn.

I don't think they are designed for that but if you were to bypass the controller and checked to be sure the applied current was correct it would probably work. Just a guess.

hello Marvin. No, the connector is only for automotive cooling, connections are different

If you are talking about a home split a/c system then this particular manifold gauge is not setup for that, and also I think the only systems that use R-134a are automobiles. The hose end fittings are also different.Hope this helps

There are 4 adapters but there is only one that you will need to convert to R134a.
