Great for tools and equipment

Good solid vacuum pump, can't complain about the price. I believe in supporting local suppliers but for the price I had to.

Good product for air conditioning line repair tools

I bought this vacuum pump to replace the A/C compressor in my car and charge the air conditioner. It has worked well because the whole system has worked well so far.

Pros
  • Humanized design
Cons
  • Hard to say

How to get oil for this tool!

This pump does NOTHING for me at the moment. I received it with about half a bottle of oil, which isn't enough for the pump to work. I can't find the HFV32 high speed vacuum oil!

Pros
  • Broad application
Cons
  • Some disadvantages

Worked best in A/C line repair tools

I did a lot of research and finally settled on this pump. I used it to vacuum a mini split unit and it got it down to -30psi. Crafting requires a minimum of -10 but is awesome. What is confusing is that it has two oil filler caps. You can use any of them, but you'll have to guess why and which ones to use until you come to the conclusion that it doesn't matter! But it is one of the screw head. Otherwise it worked great! There was just enough oil in the kit to fill the MAX line, so don't spill…

Pros
  • High efficiency
Cons
  • Negative result available
