    I just ordered the Appion valve core remover tool from a seller on Ebay, was curious if I should be able to remove the cores from a live pressurized 410A system and the close off valve be able to hold the refrigerant in?!

    Yes, check the plunger that grabs the schrader on a couple different schraders before trying it live. I've had trouble with mine grabbing the core properly so I always use my YJ plunger to remove/install the schraders under pressure.

    It will if there is room to use the dang thing. Make sure you have a back up plan.

    I have had that challenge on Rheem/Rudd units. For the most part you always need a back up plan when you remove a core. Worse case is you have to recover through the side port if you cannot get the core out or it breaks. It does happen, but not often.
    JLB,

    If these are the valves you are talking about the valves and tool are made by JB industry and that whole thing i am holding in the picture is what you have to change. I just pump down ad a few psi refrigerant and change it real quick. The tool is 500$
    They are called Core Max.

    Also if you know who sells the cores.
