XtremepowerUS 3.5CFM 1/4HP HVAC Vacuum Pump R134a R12 R22 R410a A/C Refrigeration Set AC Manifold Gauge R134 Can Tap Carrying Tote

After watching a long list of mini split installs..one of them had this pump as part of their links..I never installed a mini split before and this pump has worked perfectly for my install and I will use it for future installs. For the price this was perfect. The storage bag is a perfect addition. Bag feels very durable as well as the pump and gages.

This gauge set works perfect for me. I can't see any reason to give less than five stars. I used this set on a residential heat pump and it worked fine, no leaks anywhere including the hose connections. The gauges are clear and readable. I don't know the life of the plastic knobs but they seem pretty sturdy. The case is big enough for me to throw in all my adapters. For now I like it! If I find any problems with this gauge set I will update.

This item was perfectly priced, functionally as advertised, and delivered on time. I used it to replace the refrigerant in one of my cars and it paid for itself with that one usage.

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.

Product runs well and is satisfactory if they give one extra bottle of oil is amazing

For the price, these have been great to me. You just may need an adapter for the Vacuum line as it is larger then most ports on vacuum pumps, think I needed a 3/8 adapter for it. But besides that I having been using the crap out of them. I do Residential/Commercial HVAC and I use these for when I do my side work and they have worked great. No issues after being used near 100 times by now already. Decent budget gauge set but we'll see if they can still hold together like my several year old Yellow Jackets.

There's nothing wrong with the kit it works great, BUT you will need this adapter in order to get the R134A into any car, the fitting can't be put directly into the can tap. Even if it fits, you won't be able to get any refrigerant into the car without this adapter. You can find this adapter at autozone for just $3

Nice unit
