HCPRO HCEVCK438 HVAC Valve Core Removal Tool – Quick Flow Vacuum Rated, 1/4” Female x 3/8” Male with 1/4” Side Port, Brass Valve Core Remover for R410A R22 Refrigeration & A/C Systems

This tool is very easy to use, the quality is great and even better than a lot of the top known brands. I'm buying another one because the value for my money is worth it! This tool makes charging and recovering so much easier and faster. Just get it!

Well made however, be sure to notice this item has 1 (one) 1/4" and 1 (one) 3/8" tap instead of 2 (two) 1/4".

After used in fourth time, the gaskets start leaking, do not hold vacuum…

I bought this a while back and since I'm not pulling vacuum very often I didn't have very much occasion to use it. Used it for the first time a couple of weeks ago and it helps me pull a deep vacuum and half the time I expected it to. But the second time I went to use it I tried to tighten it onto the unit, and the ring inside failed and the piece just fell apart!
