Can I use this and an R22/R134 gauge set to just vacuum out the lines prior to installing a mini split A/C unit or do I need to get an R410 set?

This adapter and the gauge set and a vacuum pump will allow you to vacuum out the lines. The unit itself is pre-charged with enough refrigerant to supply the line sets and inside evaporators. Some people don't even bother to evacuate the system and the unit functions, but it will be better if air, moisture etc. are removed from the system before opening the condenser unit valves to charge the system. Also, by evacuating the system you can check for leaks before you charge the system. I evacuated my system before charging and everything works great. Remember that this is a split system and both sides require evacuation as they are essentially separate units. This adapter and the gauge set and a vacuum pump will allow you to vacuum out the lines.

The hose adapters are not the same, the complete set of the right hoses was cheap enough. I bought a separate 45 degree adapter due to space restrictions.

You can use hook and loop or psa depending on what backing pad you buy. I think it comes with a hook and loop one but can't quite remember. My compressor is 85 cfm but I am sure it could run with as little as 10 cfm or so, THis is a bit of a guess. I have bought loads of these in my time and won't by anything else

Used 3/4" line. Would probably not be good to use a smaller line, but check the Rheem specifications and installation requirements.

No. These gauges don't read high enough to measure the full range of what 410a can run. It's a much higher pressure refrigerant than r22 which is what the gauges are designed for.

U can use these manifolds for any hvac system. The gauges are what u will need to watch. Gauges depend on what type of refrigerant you are using. Exp. if u are using 134a for a car u need 134a gauges plus the car adaptors for hoses. If u are using the manifold for 410 or r22 u will need gauges for 410 or R22

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

Sure, attach to the low (suction) side and turn on the A/C... that's what I did.... been at least two years and still cold!!! Before I used this stuff, I had to recharge the system every few weeks.... lucky for me I got the R134 for free.... but still!!! This stuff really works!!

Thank you for your question in regard to the tank converter. The purpose of this converter is so that the 134A 1/2" ACME thread can be converted to SAE 1/4" R12. R134A tanks or 12oz can will have the 1/2" ACME thread and R12 will have the 1/4" SAE threqd . Commonly, these converters are used when R12 manifold gauges are used in place of R134A gauges if that is what is on hand or the vehicle serviced is a retro fit and using R12 gauges is preferred when filling the A/C system with 134A . The original R12 14 oz cans were 1/4" SAE thread and the newer 134A 12 oz cans are 1/2" ACME thread . The same is for the tanks of R12 and R134A . So , in order to physically make connection with R12 manifold gauge sets , vacuum pumps or other equiptment with R134A freon or any 134A fittings ( equiptment or vehicles ) , the R134A / R12 converter must be used. Conversely , there is also a converter for the opposite , from R12 1/4" SAE to R134A 1/2" ACME if R134A manifold gauges or equiptment are used. There are even adapters for different service couplings ( r134a or r12 ) when alternating gauges accordingly. Primarily , anytime an R12 and R134A thread must be joined , these two thread measurements must be taken into consideration for the proper adapter to make connection on gauges , hoses , vacuum pumps and equiptment , vehicles , ETC. Hope this explanation serves to clarify the converters purpose and further explain A/C service equiptment use.

You will need a adapter for the can from R-12 to R-134 and the hoses all come with standard R-12 fittings. What size those are I don't know but you are using all the R-12 fittings then you will be good to go. On a side note these are pretty good gages as long as you treat them like a instrument not a tool box tool.

You don't need to if your 1/4 in hose has a male end to screw the 1/4in braided hose that comes with the airbrush to. Make sure to set your compressor Down to 20 to 25psi before spraying though.

Never attempt to recharge thru the pump. No additional hose is necessary if you have a 3 hose kit w/gauges (Blue/Yellow/Red). After obtaining a full vacuum you should Close the valves (usually Blue & Red) on your hose kit then Disconnect the pump vacuum line (usually Yellow) and attach it to the can using the correct adapter for your R-134a or R-12 can. The adapter is used to pierce the can and allows for storage of any unused refrigerant. Open the valve on the can then open the Blue valve to recharge following the instructions with your hose/gauge kit. Remember to close the Blue valve when you change cans or you will discharge the refrigerant you just added. Sorry if this was a bit more than you asked but maybe it will help someone else as well.

Hi, when i got them it said they a good for R-12, R-22, R-502. But i am working on different kind off equipment and using for R-414 like regural fridge and R-410 refrigerant. I just need to see pressure on the low and high side. I also both separate gauges to have extra in local store for 15$ each in united refrigeration inc. in longwood. I hope this is helpful.

Usually PVE or POE type oil (depending on the AC manufacturer's instructions.) Do NOT use WD40 or vacuum pump oil. It will void your AC's warranty and could cause premature compressor failure.

If you are installing the system, you will need these 3/8" adapters. Most charging hoses are 1/4" and they fit most heat pumps and air conditioners but not the splits.

The gauges are different, one does R22, R404A, R410A, the other is R22, R134A, R404A. Same manifold body on both.

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.

This although somewhat different then a residential "split system" still requires most of the tools and equipment required to install a split system. Vacuum pump, gauges, flaring tool, some electrical stuff generally-just to mention a few. It is by no means a window unit that you just plug in and go.
