Will this fit other Quick Mill models like the Anita, Andreja, or Silvano? This specific knob profile is custom-tailored for the unique aesthetic and valve spacing of the Quick Mill Pop-Up model. Please verify your machine's valve stem connection before purchasing, as other models may use different shaft configurations. How do I install this replacement knob? Installation is straightforward. Turn off your espresso machine and let it cool completely. Back out the small set-screw located on the side of the existing knob, slide the old knob off the D-shaft or round shaft, push the new assembly firmly into place, and securely tighten the set-screw. Is the metal cap prone to tarnishing or peeling over time? Not at all. The cap is finished with a marine-grade chrome electroplating process, designed to withstand continuous exposure to high heat, humidity, and moisture common around espresso steam wands without tarnishing or flaking.
