VEVOR Vacuum Pump 3.6CFM 1/4 HP Single Stage HVAC A/C Refrigeration Kit 5PA Ultimate Vacuum Manifold Gauge Set R12 R22 R134a R404A, Manifold Gauge and 5ft Hose for Air Conditioning Systems

Good product. Great moter

Great Value for the money.All in all, the Pump works nicely. But did have Oil all over Pump and Packaging. could be Shipped and Handled a bit Better and Prefessional.Guages are functional and the 4-way connects are very convienent and useful. only issue was regarding the Freon Caging and Connectors. The valve and assembly dont always align as intended have to make adjustments here and there.Like the the hard case and carrying bag, really nice toucb for especially the value at which paid. must say all and all though. it served its function and i was able to draw a proper vaccum, inject the required oil and freon with very little issues. will most definitely purchase from again.

The gauges are really nice I gotta say. As for the pump it only pumps down to 650 microns and won’t go any lower. I hooked a digital micron gauge up while evacuating and it wouldn’t go below 650 so I thought to myself how can I have a leak I did a nitrogen pressure test before and It held pressure for 2 hours no problem. I then put the micron gauge directly on the pump and turned it on and it only went to 650 so I knew it was the pump and not a leak especially since it was also holding the vacuum. The gauges are well constructed and are very accurate. If you’re buying this for a mini split it will work because ASHRAE recommends evacuation to below 1000 microns for moisture removal so 650 is acceptable. Overall it’s okay. If you can buy the gauges separately I would because they really are good quality and Try and find a different pump. Unless you’re doing a mini split then this should be okay.

Instruction should show where fittings goes. Not as clear.

Out of the box this item does not contain enough vacuum oil to use. The pump has "some" oil in it, but it was not half full and it was not up to the minimum oil line. I had to stop my project; run down to the store, and buy vacuum pump oil before I could use it. As a packaged item, I expect things to be either A) ready to use or B) come with a small bottle of oil I can add. Other consumers should plan on ordering pump oil if you want to use this pump.
