Stark USA Manifold Gauge Set R410A R22 R404A HVAC A/C Refrigeration Charging Service Diagnostic Refrigerants 3 Way AC Freon Recharge with 5ft Hose

I bought this for a mini split install. Worked as needed very well.

Get’s the job done for a great price. I only needed this to install 2 R410a minisplit systems so I did not want to spend a lot just to pressure test and vacuum out the systems. It’s clearly not of the highest quality like some of the more expensive ones as the hoses and gaugues seem cheaply made. You may want to spend the extra money if you are using it professionally. However, this one worked perfectly for me for the few times that I needed it. Thanks for the deal.

A terrible product. The hoses have a hard white gasket that won’t let the pin depressor contact the Shrader valve pin. Neither the red or the blue hose would allow the depressor to push the pin and so the gauges both read zero. I removed the hoses and replaced them with two old hoses I used to use for R-22 and immediately the Shrader pins depressed and I had gauge pressure. I tried to use the yellow charging hose to add R-410a and liquid refrigerant leaked around the treads. I was unable to hand-tighten it enough to stop the leak so I replaced it with the remaining R-22 hose which worked fine. I don’t know the reason for the hard white gaskets but they are CRAP. I’m going to return them and get a better set. I can’t speak to the reliability of the gauges themselves (they worked for me this time) but the manufacturer’s choice regarding the hoses makes them suspect to me as well. For the record I do have the EPA Universal Technician certification.

Let me start out by saying I am not a professional A/C guy. I am however a contractor and have done home repairs for over 45 years. My A/C had a very slow leak and would start getting ice on my coils inside so I knew my system was getting low. After quotes as high as $100 a pound of 410a freon and after watching them put Freon in my system several times I decide to get 25 pounds of Freon, these gauges and a can of super sealer. For $10 I bought a kindle version of 410a information guide. Seem pretty simple and was in no hurry with my 10 year old system. I took my time followed all safety precautions and charge my system my self. Gauges work perfect. Clearly not pricey gauges but they give you all the numbers needed to fill the system along with all the fitting to attach to the tank of Freon and gates to do a slow and careful refill. My system never got so low that it would not cool but I am sure I put 5 lb in it which would of cost me $500. After following the instructions of the super sealer and dryer I added it to my system. So far my A/C works the best it ever has and seems to be maintaining the pressures. Thank you Amazon for making it easy to get my cool on.

Item works as needed. Clear to understand. Fast delivery.

Be careful with this one. "Pressure gauges might need to be zeroed before each use"...from their limited "manual". High side pressure is "off". Check all hoses. One of mine came open on each end! Valves can be completely unscrewed from block, no "stop". Suspect issues with this one applicable to all gauge sets in this price range.

it works

Product worked as designed and appears to be well made. I missed that it came with adapters for R-410A (Mini-Split) system, so I'll have to return the one I got. Also came with extra seals for the hose ends. Not much in the way of instructions, but if you need those, you probably shouldn't be buying this.
