This is a nice concept but it only worked on my high side port

The low side port was in an awkward location where i couldnt get this tool to fit into

Very simple to use and lost zero refrigerant

On both valves the pressure of the system pushes the tool outward so you have to keep a slight constant pressure to screw and unscrew the valves

Cant speak for durability because i only used this once and am hoping to not need it again
