If I get an adapter, does having an R410A ac system and a R134A Manifold Gauge cause an issue with the Manifold Gauge to not read properly?

There's no reason I can think of why that would be a problem. I bought mine to use for both.

low and hi-pressure are the same regardless, the difference is the markings on the gauges and the biggest is the different reactance of ambient tempature on the freon itself. Each freon pressure is different to the ambient tempature, but pressure readings are still the same pressure the gauge reads.

If the adapter didn't come with the unit you're SOL. Go back to the store where you bought it and return it or maybe you can find another unit on ebay or Craigs list. I don't think much of the unit anyway.

This adapter is not intended for use with these hoses. The 410 adapter attaches to the new style service port allowing the use of the old design hoses. to quote from the description, "Converts new R410a style 5/16 SAE service ports to accept older 1/4 SAE gauge hoses". The FJC kit is designed with the R134A design fittings on the hoses, different design from 1/4 SAE gauge hose fittings

You will need to get the R410a converter. Just search for mini split converter or adapter and you will see them on amazon. I bought one for like $10 - $15 bucks. Product description of one is "Ductless Mini Split System charging vacuum port adapter, Converts new R410a style 5/16 SAE service ports to accept older 1/4 SAE gauge hoses."

I am sorry but I have not experienced a problem with the adapter. I would think Robinair would be able to help. Sorry.

It is 5/16" SAE... Like most newer R410a systems. If you have 1/4 inch gauge set, you need an adapter.

I had the same issue and had to replace the AC adapter. I bought a universal one at Best Buy made by dynex that did the truck and cleared it right up.

Says right in description r22 134a and 404a no on 410a they do make a titan set of gauges that do 410a just read item desc

If your question is, "Will these hoses work on R134 Automotive A/C", The answer is NO not without an adaptor set to make the connection to the car but the will fit to any standard 1/4" flair Manifold Gauge set for all types of refrigerants and oils. Hope this helps!

The only one specifically stated to not use it on is R410a. It should work fine for R134a.

Yes but you need too buy the convert adapter and clean or recovery the old R12 and fill whith R134a

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.

Never had a problem with the adapter. I never read the part about the lead.

I would suggest contacting the mfg to see if they recommend using an adapter.

I'm not sure. Never heard of R410a. I'd assume the thread pitch is equivalent to an R12a. So If the thread pitch matches your adapter I don't see why it wouldn't work.

Be sure the adaptor you bought is 6volts DC (not AC) and that the center conductor of the plug that goes into you radio is the negative conductor (this is a bit unusual)

Mine works fine, but I had also purchased the one that the ac adaptor plugs directly into the device, and the AC adaptor was bad. If you have a multi-tester, make sure the ac adaptor is working.
