The Quick Mill joystick assemblies are compatible with many Italian home espresso machines, not just those made by Quick Mill. Both the hot water wand and steam wand are 3/8" British Standard Pipe Thread (BSPP) where they attach to the delivery pipe from your service boiler (steam boiler). If your delivery pipe from your service boiler has a concave end then you can install these Quick Mill joystick assemblies directly on your machine with no adapter required! If your delivery pipe from your service boiler has a convex compression end, you will need to install the valve thread adapter to accommodate these assemblies' concave end.
End of the knob to the machine's front body panel: 6.25"
Top of steam wand to tip: 9.50"
