This 2008 swivel valve allows the wand to rotate 360 degrees.
It is sold complete, ready to install, (nut and washer not included your existing one must be re-used) and includes a wand tip with ONE hole.
It can also be used on pre-2008 machines as a complete replacement. Both older and newer style knobs fit this valve.
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.
