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 Matt Hamilton

Revainrating 5 out of 5

Had to go through 3 to get a good one. Serves its purpose.

I had to order 3 to get a good one. One had a nick on the side port, the other had defects on the shaft. The one I kept worked perfectly, good value for money. One thing I would do differently is rotate the side port 180 degrees so the shut off valve is in the front instead of the back when connecting to most air conditioners.

Pros
  • Great design
Cons
  • Crumpled
