Rancilio OEM Single Portafilter Spout – 3/8" BSP Genuine Rancilio replacement spout for single portafilters, threading directly into the portafilter body with a 3/8" BSP thread. COMPATIBILITY Fits: Rancilio single portafilters (3/8" BSP thread) INSTALLATION Removing the old spout can be genuinely stubborn, plan on using a bench vice, not just hand tools. PRO TIPS The factory spout is often installed with thread sealant and torqued hard, so don't fight it with pliers alone, clamp the portafilter body in a bench vice with soft, scratch-resistant jaws (wood blocks or leather-faced jaws) and use a wrench on the spout to break it free without marring the finish. Apply a small amount of PTFE tape or anti-seize on the new spout's threads before installing so it doesn't gall or over-tighten, keeping it removable next time.
