Nuova Simonelli New Articulating Steam Wand Nut Kit A complete steam wand nut kit for Nuova Simonelli's articulating wand, covering both the standard-height nut and the taller Aurelia II version in one kit, handy since it's not always obvious which height your machine needs until you're mid-repair. SPECIFICATIONS Includes: S_969, S02280037, S_309, S_259, S_226, and S_7800 Nuova Simonelli #01000101.B (older/standard) and #01000101.AB (newer/Aurelia II) COMPATIBILITY Fits: Nuova Simonelli articulating steam wands, both standard and Aurelia II height nut versions INSTALLATION Doable as a DIY job, but the PTFE lower O-ring requires patience since it doesn't stretch like rubber. PRO TIPS Disassemble in this order to protect the PTFE O-ring: tip first, then the rubber heat guard, then the nut, and reassemble in reverse. Pulling the nut before the heat guard is the most common cause of a torn gasket during this swap.
