can these gauges be used with r12- r134a

yes it is for r-22 and r-134a i have used these gauges for other types too like 404a 410a and much more so i would purchase these, also r-12 is phased out meaning not that common now a days but you should get these gauges.

Hi Edward,Yes, you can still use the gauge. You will need a two stage regulator that has a POL inlet connection. Your gauge would hook inline between your tank and then the regulator.

This particular set is for R22. For cars using R134a you need a set that has the special automotive quick connect adaptors on the hoses. This set is only good for older residential air conditioners.

No. This manifold gauge does not have R410 on its dials therefore it will not work.

You should be able to use just about any wire with the same gauge as the ones attached to the sensors, since the current going through is minimal and overheating is not an issue...

If you have an old valve-manifold set with gauges for putting R12 in an older a/c system these couplers have the male R12 Schrader-valve style fitting to attach to your old (R12) gauge set. Then you can snap the other end of the coupler on the R134a fitting on your car. I used them to convert my old R12 gauge set (2-gauges, 2-valves, 3-hoses) for use on the newer R134a systems. Worked fine. Only other thing you might need is a new style piercing valve for the small R134a cans. If your R12 gauges are marked with "normal" pressure/suction zones for R12 they will need to be corrected for R134a. Just do a search on line for correct pressure/temp data for R134a. Hope that helps.

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.

Yes, they will accommodate 12 gauge depending on the thickness of the housing (or coating the wire is in)., 12 gauge does not determine the total size of the wire but based on the dimensions of the wire and clip they will work

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

Yes, but the fittings for the R12 systems are a different size so you will need an adapter.

That's the measurement of mine and they worked great. As long as the ends are 13mm. Should be fine.

Don't know about r22. It let me adapt my automotive a/c gauge fill hose from r12 to134a. Hope this helps

I purchased adapter for my old vacum pump which was a 5/16 for R12 and now can use for the R134 which is 1/2 which saved me from buying a new vacum pump.

Its worth saying that a car that used R12 can be converted to R134a but that needs to be done by a professional unless you know the procedure. You can't just fill it with different stuff and expect it to work. That being said if you can get it filled with R12 do so that stuff got colder and lasted longer.

Hi Paul, this kit can also be used on R12 valves. It has a special adapter.

Yes but you need too buy the convert set and clean or recovery all the old R12 before you fill the R134

Yes they do. Conventional quick connects like all R-134-A adaptors. I paid 49 dollars for a nice gauge set at Harbor Freight and use that now instead of my R-12 gauges with these adaptors. Comes in a nice box too. Not a whole lot of difference in price and the gauge reflects the actual pressures.
