Customer Reviews for 4CFM 1/4HP Rotary Vane Vacuum Pump + R134A Manifold Gauge Tester Charging +Hose

Product does what it’s suppose to do !!! Would purchase again. Terrific price and was able to recharge refrigerator without difficulty!!

Very easy to use instrumentation and better quality than other comprable brands out there.Very self- explanatory. Really like the hard case which protect and stores easily.

Vacuum pump worked fine. The yellow line of the AC manifold gauges will not connect to any can taps. Unless I'm just doing something completely wrong. I ended up having to rent gauges from a parts store to get the job done. I could not get the yellow line to connect to a can no matter how much I tried. The fittings just aren't the same.

Works as it should. Used on a mini split

I used this to install a mini split and it did great, my biggest complain is the oil leaked pretty bad so if you're using it on any indoor application I would put a piece of cardboard underneath it, otherwise gets the job done. I like the case and compartments to store when not in use.

Included more than I expected. Did the job. I replaced my a/c compressor and need to get it charged. Ordered this and pulled a vacuum and charged it cheaper than any shop

Connected easy to tank and vacuumed it down in about 15 minutes. Nice gauge set included, lines could be wider for faster performance. Overall neat machine. Job done, no issues.

I have an 8 year old Chevy Volt that ran out of refrigerant. Not only is it uncomfortable to drive on a hot day, but the electric vehicle battery cooling system also relies on the AC system for battery cooling in extreme heat. I used the vacuum pump to both confirm the AC system can be recharged (isn't leaking badly enough) and I used it to prepare for the charge. Of course, I used the gauges to perform and confirm my vacuum and charge. I did a video on this if you are interested in learning how to use this set: https://youtu.be/YXoSc2X3a3Y

I have used it a few times so far. It works well. Make sure you pay attention to where your valves are on your hose when connecting it.

Awesome product. Was easy to use and it works well.it arrived extremely fast........................
