Nuova Simonelli Steam Wand & Valve Body O-ring A 0117 EPDM o-ring that shows up in four different places on Nuova Simonelli and Victoria Arduino equipment: the upper steam wand nut, the steam valve-to-body fitting, the retention valve, and the heat exchangers. Because it's used so widely, it's worth keeping a few on hand. SPECIFICATIONS O-ring 0117, EPDM rubber COMPATIBILITY Fits: Nuova Simonelli and Victoria Arduino machines using this o-ring in the steam wand, steam valve, retention valve, or heat exchanger Replaces: Nuova Simonelli/Victoria Arduino 02280011, Nuova Simonelli 18010551, Brugnetti-Aurora 000215, Elektra 00113035, San Marco 109114 Works with: steam wand nut, steam valve body, retention valve, and heat exchanger assemblies INSTALLATION Simple DIY swap with basic hand tools. PRO TIPS Because this same o-ring is used in four separate locations, if you're doing a steam valve service, order more than one, it's common to need two or three at once rather than a single piece.
