La Marzocco Removable Portafilter Spout O-Ring, Set of Two Replacement o-ring set for La Marzocco's removable "Strada"-style portafilter spouts — one of each size included so you don't have to identify which one you need. SPECIFICATIONS La Marzocco part #: H.1.017/PAIR Set includes one of each size COMPATIBILITY Fits: La Marzocco "Strada"-style removable portafilter spouts Does NOT fit: Current La Marzocco portafilters with fixed (non-removable) spouts INSTALLATION Simple DIY replacement — pull the spout, swap the o-ring, and reseat. PRO TIPS Not sure if your portafilter uses a removable spout? Check whether the spout pulls off by hand — La Marzocco's newer fixed-spout portafilters don't use this o-ring at all. Replace this o-ring any time the spout feels loose or starts dripping at the base — it's a low-cost fix compared to replacing the whole spout.
