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.

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.

The blue hose has a manufacturing defect. The center insert (that engages the Schrader valve) is threaded too far so it does NOT engage the Schrader valve. I fixed this by using a round-nose pliers to mash the threads in the middle of the insert so that it doesn't screw into the hose quite as far. These hoses do come with a couple of extra rubber/plastic gaskets. I cut one down trying to fix the problem with the blue hose, and I lost one, and my local HVAC supply place doesn't carry this style. So if I lose one more, my new hoses will be as useful as a pile of... I contacted the seller about both these issues. They seemed eager to help, at first, but after several emails I was informed that they don't carry any spare parts.I pretty sure I wouldn't have had these problems if I had spent the extra money for the yellow jackets.

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.

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

Not the greatest of quality, but it got me through a time when I needed Freon every day. One of the hoses ends broke off pretty quickly.

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.
