4CFM 1/3HP Vacuum Pump HVAC Refrigeration Kit AC Manifold Gauge Set

The pump still works, the gauges still read, but one knob is mostly stripped out. One of the connectors' gaskets wore out, rendering it unusable. For three years of use, at this price I would buy it again.

I have been looking for a good set of gauges for a long time. Really like the case. It will protect and keep everything together.

Excellent product! Not just a great price but a great product that I will use many times.

This pump is good, no question about it. But be careful ordering this kind of item as it comes with oil in which Amazon considers it a hazardous liquid, which can't be refunded. Order at your own risk. Next time I rather purchase it locally.

no instruction came with this unit. plus it does not come with the top valve refrigerant opener. was no mention that you have to order this part separately. did not know this until I went to use this kit this week. had to use the one that you get when you buy freon with a single can.

I'll be damned if I will pay $600 for someone to pull a vacuum on a mini split i install for myself. Normal procedure is you run a bubble test with nitrogen before you pull your vacuum.but you probably aren't going to do that. If you pull the vacuum and it does not hold, you probably won't know where the leak is coming from. I pulled it and there was a tiny leak. Could have been in the hoses leading to the vacuum.for all i knew. But it was a very small leak. So after i tightened everything as best i could i pulled the vacuum again and released the refrigerants into the line. Then i ran the bubble test knowing it was only going to leak a tiny amount if at all. I found that tiny leak and tightened the crap out of that fitting. (It always says you need a torque wrench but I have never used one and i have installed 5 mini splits without a problem. You can tighten hard just don't be a really strong dude and try to kill it). PS - you can roll up your extra lineset if you want to. I rolled up about 4-6 feet. Blows plenty cold. Unless you feel good about your copper line flaring skills, you can roll up the excess and its not going to matter much. So, make sure you have thread goo for the fittings, the adapter for the yellow line where it fits to the mini and some bubble testing fluid. You can make your own with some dish liquid if you insist on being enterprising. Make sure you have small wrenches and hold both sides of the fitting when you tighten. Make damn sure your drain line always runs down. You got it!

works great easy to store

For some of you that claim to be Nuclear Engineers or what ever your title, please stop blowing smoke.I bought because I have two projects to accomplish.1. To replace a lower side hose in my GM car. Pump and gauges worked like a charm after watching a few YouTube videos.2. Installing Ductless Mini Split unit in my garageEverything so far has worked the way it suppose to work.

This pump works great.

Did have to go to YouTube for help. Did the trick.

Exelente repuesto lo recomiendo 100%

Me a funcionado exelente gracias

Works perfect. Pulled a vacuum easily.

The product works as expected. I used it to empty out my AC line in my 2007 VW Jetta so that I could recharge. AC was blowing hot and my pressure was reading full. Just wanted to try the recharge prior to moving into more expensive options like the compressor or what not. The vacuum worked great. I had a difficult time getting the gauges to fit right on my low and high points but I think that was honestly just me being skeptical about using too much pressure to lock them in. I eventually got them on and empty out my unit in less than a minute. Refilled with refrigerant and now it’s been blowing cold for 4 days.The seller was extremely helpful and professional. I accidentally ordered twice and didn’t realize until they both shipped. They were able to intercept the package for a small fee and refunded the remaining amount. It was only 1 day from the time I reached out until I got a reply and my refund.Would recommend.

I like the kid had everything I needed

This is an inexpensive set of gauges and pump. Yes the hoses are a little short, but everything worked perfectly for me. I've recouped the money I spent on it in saved repair costs for my truck and my wife's car. If I never use it again I'm still ahead. The pump worked fine. The connectors all fit well. The gauges are reasonably accurate. Follow the instructions for oiling the pump. No this is not a professional set that will hold up to commercial use, but that is not what most of us will buy it for. For home use once or twice a year it is just fine. (Buy a can tap).

great for home use

Thank you . Save lotta money with charging my Air condition

Good value for the money. I bought this kit to install a mini split air conditioner. It worked perfectly for that. It's small and light weight yet has plenty of power.

I use these every day working on cars. Good quality for the money.

works as described

Great pump and manifold gauges, hoses too short. But overall does a good job.

Muy bueno

Worked great pulling down vacuum on my AC doing an R134 conversion. Pulled down vacuum for well over an hour with no issues

Worked great!

All works well. The hoses are shorter than expected but overall good product

Love it!

Good

Works Great!

good quality for the price, practical kit and easy handling saving you expenses with a technician ...

Perfect

very handy tool set .I use the vacuum pump for hyd also

I asked if the seller could expedite the shipment, even for a couple extra dollars and the answer was flatly no. With that being said, overall I was very happy with this unit for the price and it did the job well. The one thing I did notice was that there is no freon 134a can valve included and when I did go out and purchase a can valve I could not get it to seal properly to the hoses on this unit. This is probably not the fault of this kit, I just wanted to make sure that any potential buyers knew about needing the can valve. Final verdict: A good unit for the money, hoses are adequate, but on the shorter side. Don't expect Prime speed shipping and don't forget to purchase a can valve if you don't have one!

I have used this kit three times so long term use not known. This has 1/4" flare hoses and fittings with 1/4" to 1/2" R134a adapters on the quick connect fittings. The hoses are 36" length which worked out OK. I separately purchased a 1/4" to 1/2" adapter for the cans of R134a. I needed a little PAG oil on all the rubber gaskets to make a good seal. The single stage pump worked good. It took just a couple minutes to bring the vacuum pressure to -29. I ran one vacuum for 1.5 hours and the pump got hot to touch. Then again it was also 91 degrees outside. If I was a professional AC mechanic I would have much better quality tools. This is a price/quality sweet spot for what I needed. Bottom line it has paid for it's self already by not having to go to an AC mechanic.

Worked Perfectly.

Excelente
