Review on 🔧 Efficient R134A Valve Core High Low Pressure Tool for Automotive Air Conditioning: SY66 Quick Remover Installer by Michael Heidelberg

The tool is of high quality. But it doesn't work. As many users of such tools note, the tool does not hold the bar. However, it is quite easy to set up. Gently tap the end of the stick grab to reduce the gap and it will start grabbing the stick. Just make sure you don't overdo it. I did just that, grabbed the Schrader valve and pulled it all the way out, but to my disappointment, the tool's ball valve would not close. The schrader valve was on the way because the tool body is too short.
