Used this to pull a vacuum on my AC system before recharging. System held a solid vacuum. Vacuum hose connected to pump with no problem and has a nice tight fit. Need to put accompanying oil in unit after it is unpacked and before first use.

Pulled a blind bearing out of a NP228 rear case. 59.5mm inside diameter. Was able to tighten the biggest collet and it grabbed the bearing and used the counter stay to ease it on out.
