1/4" Standard Fitting Valve Core Remover and Installer with 1/4" standard fitting Access Port for HVAC-R Mastercool Part Number 91496.
Temporary removal of service valve core eliminates the restriction it creates and provides full flow of refrigerant and vacuum during recovery, evacuation and recharge. You will save valuable service time. Change the valve core without loosing any refrigerant.
Great product one of the best I’ve seen yet very stout should last for decades

A great tool for changing ac schrader valves. It worked perfectly and allowed me to change both high and low pressure valves within minutes with no freon loss.
