VEVOR Vacuum Pump 12CFM 1 HP Single Stage Air Conditioning Vacuum Pump 110V 5PA Ultimate Vacuum Refrigerant HVAC Air Tool Rotary Vane Vacuum Pump for Automobile Vacuum Evacuation

Used pump for 3 months and it worked great. Had an issue with while pulling a vacuum where internal wires melted and pump quit working. I reached out to VEVOR and sent pictures to which they replied within a couple of days and actually sent me another vacuum pump at no charge. I haven’t seen customer service like this in a long time. Refreshing to know some companies still take pride in themselves. Way to go VEVOR

I haven't put the pump in use yet. I knew/saw that it was a 3/8" flair and 1/4' flair on the pump. (in the ad) But I knew foreign firms often mislabel their ads. So I took the time to ask if indeed it was 3/8 & 1/4. I just received the pump and it's 1/4 acme and 1/4" flair. AT THE VERY LEAST, I'm going to need to figure what fittings I need to buy to achieve 3/8, 1/4 flairs ------the reason I bought this! Quite disappointed. Not what I bought.9/9/19: this will be a progressive review. I'm an HVAC guy, and I haven't been using it quite yet because I ordered some brass fittings to get the configuration that was advertised---and I didn't get. (3/8 & 1/4) (I use the 3/8 yellow jacket brass tree) At any rate, I out oil in it today and started it up and it smokes---others have reported that too. I will leave another edit, once I put it to use. But it smokes, for sure.9/21/19It’s smoking still, but less. I ordered a series of brass fittings to refit the ports; I now have a 3/8 flair and 1/4 flair. I came up with a unique 4 hose set up with heavy duty yellow jacket Evac hoses and pulled a unit yesterday down to 67 microns. I think the pump is not a Navac, but with decent hoses and following best practices, I think this pump will be fine. (I hope) I’m using a brass Yellow Jacket tree and 2 3/8 hoses and 2 1/4 hoses. On a tight system this pump pulls down fast. I’ve added a star.As I mentioned earlier, rather than a 3/8 and 1/4 outlets as advertised, it had a 1/4 flair and a 1/4 acme. So I spent a bunch of money and rebuilt it with brass fittings. I pulled a vacuum today and when I pulled the yellow jacket tree off the pump, there was a bunch of oil. There was a baffle I would guess on the old fittings---which were the wrong size anyway. I'm CONVINCED that "made in China" will mean high quality one day. Japan made shitty radios in the 50s. Today they make Acuras. I really don't like this pump. For now, it's American made---probably NAVAC. This pump sucks.

VEVOR Vacuum pump 12CFM 1 HP does not built to last and get broke on on 3rd day. My old pump at 3 CFM performs better than stated "12" CFM VEVOR vacuum pump. Best of all , the seller did not issue refund even after a few days of proven return. Im working with Amazon now to get my money back.
