Fits: Pre-2008 steam valve (does not swivel).
We recommend replacing the two O-Rings as well.
If you’re not certain which version you have, the 2008 knob is silver in the center, so it’s a good indicator as long as no one replaced only the knob on an earlier version. The best confirmation is to measure the diameter of the steam wand tube (not the tip): PRE-2008 = 6mm; 2008-Since = 10mm.
