I need be able to disconnect the evaporator on a residential refrigerator and then put it back multiple times without having to hook up gauges/vacuum/charge the system.

I am trying to find re-sealable refrigeration fittings designed to be connected and disconnected at working pressures with no refrigerant loss.

I can turn off the fridge/let it thaw during the evaporator work, if necessary.

What sort of valving configuration or fittings should I be looking for? What is the best way to go about achieving this?
