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 quick coupler of my charging kit. Need about an extra 1/2" of space. 1. Will this item, ESR12CTG, allow me to connect to a 134a can and charge my system with 134a through the original R-12 low pressure port on the car? 2. When I am done charging the system does closing the piercing valve seal the contents in the can to permit future use?

the hose may bend ok, you'll have to try and see. The lines are typically aluminum, you may be able to bend them some to get clearance. And NO the can will bleed off in time it will not last 6 months when pierced.

The female threaded end of the device accepts the standard male thread size and type that is found on ALL cans of 134-A Refrigerant. The Blue Connector attaches to ALL systems that contain 134-A Refrigerant. Be sure to push down hard on the blue connector, so that it snaps into place.

Female is 7/16"X20 and male is 1/2" acme. The female is the old standard R12 gauge fitting and the male is the new R-134A type tyoe gauge fitting. If you have a pump with that works with old style gauge set, this will adapt that fitting to the new style gauge set with the quick connect port fittings. Hope this makes sense and helps. DWH

The downstream/output end is 1/4" SAE female, for connecting to a 1/4" SAE male service port. As such, it is a "twist on" connection. It is not a "pull back and snap on" (which would be a R134A quick connector). To clarify: This gauge is for charging systems that have a 1/4" SAE flare fitting with schrader core valve. This fitting is typical of old automobiles that use R12 refrigerant, residential AC systems using R22, and small appliances like freezers, window units, and refrigerators that have had an access port installed (piercing style or brazed in).

Actually works on both. The pressure is reduced by one half when you use it in a six volt system. I use these all the time in my restoration shop when I am adding a fuel pump to earlier six volt cars. The addition of ethanol to gas has increased the occurrence of vapor lock on early vehicles. Adding a fuel pump back by the tank overcomes this. This pump produces about 3-4 psi on 6 volts. I haven't had any starvation problems due to volume on some pretty large engines. I have this pump working on a 1937 Cadillac limo, a 1933 v-12 Pierce Arrow, and numerous other smaller applications in the late 20's to early 40's. It should do what you want to do just fine. It's is a nice quiet, reliable pump. Actually works on both. The pressure is reduced by one half when you use it in a six volt system.

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.

I really can't answer for sure but since every low side service port I've ever seen changes with the type of refrigerant in the system I'd have to say that the connectors that come with this item won't fit something using R410a. In fact according to my research on a quick online search it seems that R134a uses a 1/4" connector while R410a seems to use a 5/16" connector but adaptors are available so the same injector can work on R-12, R134a and R-410a systems.

Unfortunately this manifold is only for HVAC systems and not automobile 134a / r12 refrigerant gas. You have to purchase Uniweld Model QAL5SM or QAL5SMA in order to use with R134a.

Sorry, I do not understand your question. For the hose/gauge shown, one end goes on the car's connection . The other end screws onto the can of refrigerant. That hose is the only one I know that fits the can. Let me know if that is not your question.

I had the same issue at first. I bought a manifold set off of amazon that was sold as an FJC but it turned out to be a cheap knock off. The hoses were all for R-12 not R-134. The quick connects for the high and low pressure side were 12 to 134 adapters and the only can tap that would fit the yellow line was an old R-12. I sent the cheap gauge set back and purchased an Interdyne AC Pro set and it works perfect.

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.

This product is meant to work with non California applications. It fits all cars with standard 134a connections, but the end that connects to the Freon can is for standard non California Freon cans. California requires a Schrader valve ( tire stem type valve) that reseals, and the thread is not quite the same. An adapter can be found to remedy that though. ( I found one at big lots of all places). I like the length of the hose but this setup comes with instructions that tell you the high side limit by ambient temperature. Very nice, it's a good tool for a quick fill up. I hope this helps. Regards, Paul This product is meant to work with non California applications.

Yes, this is compatible with R12 systems and R134a systems. Most vehicles 1992 and older are R12 systems. You will use the low side adapter included in the kit to connect to the low side port on an R12 system. If your system is a 134a system, the hose will attach directly to the low side port.

I can only vouch that it works well for R134 and R12. I haven't tried it with any thing else. Manufacturer claims it works with all refrigerants to varying degrees.

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

I cannot help you, my 1989 Honda civic was retrofitted from R-12 to R-134. The retrofit fitting adapter has it own valve stem on the low side (an extension stem and shorter) and not the same as the kit. There's another valve stem under the retrofitting (low side) adapter which could be replace by the kit. I used a tube cap valve stem remover and it work better than LR-14

I looked up a pump for your L322 RR on the Atlantic British website and came up with an identical picture to the URO one you're asking about even down to the connector. Like I stated, the Uro didn't have enough pressure to even reach the windshield. The return was easy, I stated the problem, they(Amazon) gave me a return label to print with postage paid and they credited me the original cost. Another option is to try an Anco version #67-15 of the pump,you might have better results. Try your local parts store, but go with an application for a MB ML500. Good luck! P.S. The shape of the connector is rectangle with one end rounded.
