Instruction of How to Use the Valve Core Remover/Installer:

  1. Warning: DO not force to close the valve when the steel shaft is in the valve! Damage to the ball valve may occur.
  2. Get familiar with your new tool before using it: know each part and what does it do or for, the MOST important part is to know where is the seal point, shaft-washer seal or the valve.

  3. Know the size of the valve with witch you are working on, the 5/16" adapter may be needed only if you are working on some R410a system,
    Note: the end nut on the assembly body is the 1/4" adapter itself; it goes directly to the 1/4" port; This tool does not have the correct size for car AC systems.
  4. Valve Core Removal:
    1. Assemble the too as received, with or without the 5/16"adapter.
    2. Connect the end (1/4") nut or the adapter(5/16") to the AC service port where the valve core is leaking.
    3. Note: Turn and free the shaft from the locking nut if needed to control the travel distance of the shaft.
    4. Push the shaft slowly in and let the end to engage with the valve core.
    5. Turn the shaft knob counter clockwise to disengage the valve core from the port.
    6. System pressure may help to push the shaft out through hand valve.
    7. Close the hand valve.
      WARNING: FAILURE TO CLOSE THE HAND VALVE MAY CAUSE BODILY INJURY AND LOOSE THE CHARGE OF REFRIGERANT!
    8. Loose and remove the shaft connection nut from the assembly body.
    9. The damaged valve core should be at the end of the shaft tip.
  5. Valve core installation:
    1. Insert a new valve core into the tip, just like the way it was out!
    2. Connect the shaft connection nut to the assembly body and tighten it.
    3. Open the hand valve, and push the shaft through the hand valve.
    4. Turn the shaft nob clockwise to install the new core, do not over tighten!
    5. Once the core is in place, pull the shaft out of the hand valve and close the valve.
    6. Optional: Disconnect the shaft connection nut from the assembly body.
    7. Check if its done right by slowly open the hand valve. If the pressure dissipate quickly, the core is installed right.
    8. Remove the assembly from the system port.
  6. You are done! put away your tool.

Here is a short movie of how this process is performed:
Click here to see the VIDEO clip. Q: Can I use this tool to work on car AC port valves?

A: This tool is designed for valve ports with 1/4" or 5/16" connections, these sizes are common to home, office, commercial AC systems, refrigerator/freezer/ice maker etc. Car AC ports are different and this tool DOES NOT connect to the common car AC ports(unless the ports are 1/4" or 5/16" connections).
