Review on 🔧 NewPosition 4CFM 1/3HP Air Vacuum Pump: Ultimate HVAC A/C Refrigeration Tool Kit for AC and Auto Repair with Manifold Gauge Set, R134A R22 Compatibility, and 3 Hoses by Arturo Reyes

gauges worked well although it would be nice to have an adapter to connect to the R134 bank. My problem is the same as other reviews, the breather cap came off and my garage filled with smoke (no fire, just how the oil works in the pump. The threaded breather cap is out of spec with a cast threaded hole on the oil Tank.. I had to make a small attachment to hold the cap while vacuuming my system.I should probably return it but had no motivation to drain the vacuum oil and send it in. Would recommend spending a little more and getting a better pump I was able to get it to drain my system and charge it back up after repairing the vaporizer.
