A mechanic changed my 1990 Cadillac over to 134a but did not change the low pressure port from the R-12 version. To add refrigerant I installed a low pressure adapter but there is inadequate room between the auto body and the adapter to connect the...

What you are describing is what I did with my Ranger pick up truck and why I bought this item. This item fits the tops of the Envirosafe cans which are the same as R134a cans. The threads on some of these cans are not perfect, they make millions of these cans and quality control on them isn't perfect. I found if you make sure not to cross thread them, they will work, even though you need to use extra force to make sure you get a good seal with the seal inside of the valve on this item. As far as the needle making a perfect seal for storage of the extra refrigerant in an unused can, you can't bet on it. It will hold for a while, but for how long, who knows? I think if I need to do it, this is what I will do. I think if you leave the valve on the can, of course, then connect the hose to the manifold of a gage set and the gage valves are closed securely, with all connections tight, I think this should work. The can tap with gage and hose assembly fits R12 fittings and others like on house AC, plus you can get adapters to go from R12 to R134a fittings. I also have ordered R134a right angled adapter fittings, so it will possible to also use this can tap on R134a systems. Servicing AC IS complicated, but it is a lot less so after you get into and also do some research. Hope this helps. By the way the right angled adapters of the R134a system, really do make things a lot more accessible. If you don't have a gage set, I would suggest a fitting that can be screwed into the end of the R12 fitting on this hose to block it off, IF the valve doesn't seal the can. This fitting would need to be soldered shut somehow. (I think I will do this myself. If you can't trust the valve, closing off the hose makes sense.)

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

NO!!! First, Automotive R-134a uses PAG (polyalkyleneglycol oil) whereas your residential/commercial R-134a uses POE (polyester oil). Don't mix the two. Second, it is highly illegal for anyone unlicensed to access the refrigerant in a residential/commercial HVACR system. Please consult a professional if your system needs help.

the gauge is labeled for r-22 r-12 and r-502. it wont hook up to an automotive 134a system with out adapter. not sure about r-410. the replacement for r-22 what type of system are you looking to service???

No. Domestic and automotive air conditioning systems are not compatible, unless you have an older model car that used R-12 refrigerant. Paul

My olds custom cruiser had already been converted to r134. I had a compressor seal failure so I replaced the compressor, accumulator, and orifice filter. Added pag oil, too. I think you would want to flush system prior to going with r134.

Email the company, you might need another type of adapter if your radiator has a remote fill.

on the older r12 cars, the high side port was smaller than the hose fitting, the vacuum pump adapter will fit but not work the one that will work, has a shredder.

1. Ask the dealer what they use? 2. You don't need a radiator cap adapter- Buy a new radiator cap. -- To test the radiator get a 1DXN1 universal adapter. This adapter is not made bySTANT. It must be modified (by trimming two metal burs) to get it to fit. Hope this helps. I guess we know why most motorcycles are air cooled. Ben

If your car is a 1993 model or older, yes. In '94 the change was made from R-12 to R-134a and along with it came a change to the fittings.

You wont need the POA valve (if your car still has one) and might want to upgrade your condenser to a cross flow type for improved cooling, though your original condenser will work. Just take it in to your local A/C guy so they can evacuate your system, install the compressor, refill and check for leaks. Mine works better than ever.

I returned mine. Could only get 130 PSI out of it. Connector did not leak though.

If your car has a pressure switch then very easy. For me I just had to remove pressure switch find which adapter was the correct thread and is screws right in.

I do not believe so. This valve core remover is designed for automotive R12 and home R22, and R410A systems. Your car should be using the newer 134A system and that has different ports that this valve core remover cannot attach to.

I have no idea, I'd call Rheem Tech support. They were very helpful during my install. Personally, I don't think pressure variations would be an issue, but who am I to know?

My car, a 93 Caprice 5.7, originally had r-12, but when I replaced the compressor with the AC 15-20189, with Pag 150 oil all worked well with R-134Al. I used an 80% charge of R134A with the new compressor, dyer, and the aftermarket condenser. The compressor didn't come with a high pressure switch though.

My guess would be a yes. I put it in my '95 Volvo and my 2000 Merz and all is good. This was done after sending my questions to the RP people and getting a good response. I expect MAX ATF to give me cooler operation.
