UPGRATED Version 4 Way A/C Manifold Gauge Set Fits R134A R410A R404A R22 Refrigerants with 5FT Hose, 3 Acme Tank Adapters, Adjustable Couplers and Can Tap

I was hoping this would work as well as the standard Yellow Jacket brand that HVAC technicians use. I am a homeowner, not an HVAC tech, needing to recharge my central air conditioner myself because of the shortage of HVAC techs available these days, long lead times to get service, and high prices. I was not disappointed in this manifold gauge set. In fact, I had put it away for a few of days with some liquid refrigerant locked into it, which I only noticed in the little view window after pulling the gauge set back out. The thing that occurred to me is that the refrigerant had not leaked out over all that time.The thing that I think that this kit is missing is a set of inline ball valves or thumbscrew core depressor valves. Without those, you lose all the refrigerant in the hoses when you disconnect, and disconnecting the fluid line is more messy. The kit is not advertised as having these, but I'm just pointing it out.

Works as intended 5 out of 5

Pretty decent for the money for a homeowner or handyman. Gauges could have been a little better quality as they seem like paper on the inside but they functioned properly. Hoses seem to be quality rubber and are very flexible. Fittings turned clean and all valves sealed tight. Not a bad purchase for something i may use a couple times a year.

Just used this to add a 12 oz. can of R134A freon to my sons 2004 Honda CRV. I checked the pressures of the high and low side ports of the a/c and found the system to luckily just be a little low of refrigerant. I added just a little freon at the time and then would increase engine rpm to 2500 rpm to check high pressure readings. Ended up taking the whole 12 oz. can to get the pressures at the proper level. The proper way would be to have the system evacuated and then add in the proper amount but this would have been very expensive at the price quoted to us so this was thenext best thing. I did not want to use those refrigerants with the gauge for the low pressure side, by using this manifold gauge it gives you the whole picture of what is going on and actually did not cost that much more than buying those cans with the guage, Center air vent was 76F before topping off refrigerant and isnow 41f with the outside air temp 89f with 68% humidity. This manifold gauge performed flawlessly and as expected and was very easy to use----Highly recommended !!!!

Great item. All pieces needed are in the box.AAA+++

Perfecto

This is a great set for the DIY'er. Comes with everything you need to be able to measure, fill, and bleed your A/C system. Comes in a great storage case that holds everything, and instructions on how to properly use it.

Air will pass through the vacuum port and the charge port and into the gauge and between each other but opening the left and right high and low control knobs does not actually open the valve so that anything can pass into the lines leading to the car making this gauge worthless. Currently waiting on Amazon to send a replacement.This review is for:AURELIO TECH 2020 UPGRATE Version 4 Way A/C Manifold Gauge Set Fits R134A R410A R404A R22 Refrigerants with 5FT Hose, 3 Acme Tank Adapters, Adjustable Couplers and Can TapThat was sold by Penson & Co. and shipped by Amazon.I bought the Aupoko can tap (R134A Self-Sealing Can Tap with Right Hand Thread, R134A Valve Tool Bottle Opener with 1/2" Acme Female R-H Thread and 1/4’’ SAE Male Connector, Fits for R134A Automotive Air Conditioning Charging) for use with the new self sealing since this kit doesn't come with one and it works fine with the new cans:https://www.amazon.com/gp/product/B07SZLQXV3/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1Also, watch out for the hook to hang it. Mine was not screwed all the way in and was just barely screwed on when I pulled it out of the box. If I hadn't of noticed it probably would have fell off while it was hanging on the car hood.The gauge seems like an ok set and the knobs felt solid. If it would have just worked. Maybe poor quality control or no quality control along with my bad luck. We will see with the next one.
