What is size of low pressure service port? Should we use 3/4" or 5/16" manifold gauge ? Can we use R134A manifold gauge?

You need these two items. R134A will not work. http://www.amazon.com/gp/product/B00159WZ12/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 http://www.amazon.com/gp/product/B00D96EWKQ/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

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."

Not sure what you mean wrong side. I used mine on an A/C Manifold guage set for R22. The blue connector has got to go to the low side, and the red connector to the high side. If your guages are not colored, the low side is on the left. You will notice that the blue connector will only fit on the low side of an R134a system. The low side guage will have -30, which you watch when vacuuming down, to check for leaks before recharging. I am not familiar with other type of guages, so take what you have to an ac place and they will tell you what to do, I finds them pretty helpful. Mine went right on, no problem.

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.

mine came at 5/16th, must clamp. but as Paul stated 1/4 is fine... 1/4 is the inter diameter of inlets. so pick based on the rest of your system.

! inch but you can get reducer couplings that go from 1 inch to 3/4 or 1/2. Best if you use 1 inch in though.

I used 3/4" pvc pipe, very good, powerful pumping as long as installing according to instructions provided.no problem at all.

Yes, the ball valve fittings are "low loss fittings" which should be used on all gauge manifolds hoses.

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???

The inlet & out are 1/4NPT. The most common sizes are 5/16 Hose x 1/4NPT & 3/8 Hose x 1/4 NPT

Yes. Threads fit my previous tank hose. Use or order gage for this manifold.

the product has 134 fittings but your vehicle will have R12. I bought the adapter hose with the gauge for $12 here on Amazon and it worked perfect. Hope you all the best!

You are correct. These are universal manifold gauges. They can be used with a larger commercial tank of 134a. If you are using the one lb cans typically sold for do it yourself-ers you will need a piercing valve for the can which will have an attached hose to couple to the manifold gauges.

You will need something like this. CPS Products MT2H7P5E 2V Pro-Set Manifold Gauge w/5' Premium

I used a 3/4 " line. I think the Rheem website will tell you the minimum line.

It is 1/4 npt for sure. The thread end is standard garden hose, and I think that is different from 3/4. But you can probably get an adapter at a local store or online at amazon

I don't have a gauge to know how low but I am pretty sure you can get it below 5 psi. Works close to a need valve.
