Badger 200NH & Fine Line Assembly

Hi everyone. I just bought a Badger 200-3 single action airbrush. It came with a medium nozzle. I would like to get a fine nozzle for it. I found a Badger 50-0161 Complete Head Assembly Fine at

I'm assuming that I need to get the Badger 50-0172 Needle Fine at

Is all this compatible with the 200NH & is this all that I need to do get the fine line effect out of it?? Thanks very much.
