Review on πŸ”§ 9M9 Valve Core Remover Installer Tool: SAE 1/4 & 5/16 Port for HVAC A/C - Includes 4 PCS Valve Cores with Teflon Seal (No Gas Loss) by Clint Mcloven

Revainrating 1 out of 5

Doesn't grab Schrader core

I was able to unscrew the Schrader core. But the tool fails to grip the valve and the valve gets stuck in the ball valve. As someone else mentioned: pressure pushes the valve out until it hits the ball valve and then the freon flows past the stuck valve. I can't remove the tool now because I can't screw the old valve back in.

Pros
  • Great for outdoor activities
Cons
  • Not sure
