I am repairing a Sama lever machine. The steam and water arms are junk. I want to keep the valves and am trying to figure out how to change over the tube parts. I think the connection is 1/2 inch- or 18mm?- I am not sure of the exact measurement- it is the standard size throughout the Sama machine. The parts need to come out of the machine at a very specific angle- so far the old V1 Silvia arm is the closest shape I have seen. If I cant find something off the shelf- does anyone know how I could get some made?
here is the original Sama steam arm:
