ARKSEN 4-Valve (R404A R410A R22) Manifold Gauge Diagnostic Refrigerant A/C Tester + 4CFM 1/3HP Vacuum Pump

Be aware that this is not a kit that would be found in a professional HVAC service truck, but it did exactly what I needed it to do when I installed my own 3-ton AC system. I'm skilled enough, but I'm not going to be doing HVAC much more than this. For the price and knowing I would only be using it for one job, I couldn't find a better deal. Getting the right tools is key (this kit is just the beginning), but you need to do a lot of research, have a clear understanding and put a focused plan together before you are going to effectively use them.

work good but have to buy othr fitting to work with the lines.

Don't buy these gauges, the knobs screw into a plastic insert that is used to hold knob and allow for open and close for the valve. When you try to open the valve the cheep plastic retainer comes out with the knob allowing the gas to come right out with it and burn you and vent off your gas. The very first time I used them they leaked very bad tried to adjust the knob and insert but it is so cheep you can't even fix them. Junk Junk junk

The Purchase was to service a R410A system and the connectors on the hoses provided will not hook up to a 410A system. The 410 adapters were either missing or not a part of the kit. Since there was no parts list or directions in the kit I cant make the judgment of which. I ended up hiring someone with the proper gages to service my system.

My screw up. Actually need a two stage vacuum pump (or at least I think I do. Not sellers fault. I'll use it for something else. Still be able to use manifold and lines.

Description indicates that the hose fittings are 1/4" but that is not entirely correct. One side is 1/4" but the other side is 5/16" which does not connect to standard HVAC units. Kit is completely worthless to me as I can't hook it up to my system.

Does not connect with Arksen gauges. Can't pull a vacuum using gauges. Useless and no customer support.

Product as described.Low pressure gauge not functioning.Everything else work's great.Fair price.Fast shipping

高圧側バルブが初めから斜めに取付けられていた為漏れた！取外し試しにネジ部を回してみたがネジ山がダメになっていた！初期不良だと思う輸入品はダメだね！納期に1ケ月もかかったのに！
