Mastercool 6 CFM Single Stage Vacuum Pump 90066-B

Must have pumped down 50-60 mini split heat pumps with this ,not a problem with it , changed oil in it 3-4 times and it works great…..would buy again if it gave out.

I have been using these pumps for many years, they work great to get down to a deep vacuum. I use multiple of these vacuums with 1/2 vacuum hoses on one system. Pulls down to 500 microns before you know it. I use mine for a year and then retire them with a new one, and at the price point it is worth it. The pumps still work after a year and you can flip the apex seals in the pump to get longer life out of them.

This is the exact same item as the one another brand uses. Begins with snap, and ends in on. Save them dollars.

Used it to vacuum line on a mini split, did it in less time and all is good. It's more expensive than other one,but did the job in no time. I'm very pleased with it, I was very impressed with the purchase and shipping. I received it within 48 hours of order. Thanks
