XtremepowerUS Premium 4CFM Air Vacuum Pump HVAC A/C Refrigeration Kit AC Manifold Gauge Case Set R134a Tap w/Leak Detector and Carrying Tote Bag

Fast shipping and great quality

I was concerned when buying this kit due to the negative comments. Especially, the comments where people had problems pulling a 30 HG vacuum, suggesting the pump was not powerful enough. After a bit of research, I decided that the pump should be able to pull the required vacuum, so I gave it a go.When setting up the system, I realized two quality control issues. First, the high-side (red) hose was missing it's rubber insert. I found that out the hard way, by watching the system leak down to zero after pulling a vacuum. Fortunately, the kit came with 3 extra inserts, which fixed that problem. Second, the can-tap fitting has different threads than the yellow hose. You literally cannot connect the hose to the can-tap fitting. That crisis was averted as the kit comes with a few extra fittings that can serve as adapters, but they have Schrader valves in them (I think they are for systems with a different refrigerant type). I removed the Schrader valve from one of them and used it as an adapter -- it worked (I think someone put the wrong can-tap valve in the box).I was able to pull a vacuum without issue. Within 60 seconds, or so, I was at 29 to 30 HG. After letting the system sit, confirming no leaks, I ran the pump for 45 minutes to extract any moisture. The pump did great and held the system at 29-30 HG (for those who want to know, my location was at 750' altitude, 50 degrees F, 51% humidity, and 30.22 HG air pressure). The pump smoked a little at the start, but ran clean after that. I was successful in doing a full recharge.Even though there were quality control issues, I still gave this product 5 stars as the price was fantastic considering the tool's purpose, it was easy to use, and it was able to get the job done.

The media could not be loaded. Used it on my cars a few times. Overall it’s a good product and easy to use. A/C charges are pretty good too.Only issue was the R134a can tap, it had problem with first use, as the Freon was not able to flow through freely. Then after inspection, I found that the connector to the hose was broken inside. It gave me quite some trouble while using the tool to recharge.I had to buy a new can tap at Harbor Freight to replace the bad one.
