The Rocket 2-Cup Spout is a replacement part for your Rocket Espresso portafilter. It is available along with other espresso machine and espresso grinder parts at Seattle Coffee Gear. This is an original manufacturer replacement part from Rocket Espresso in Milan, Italy.
Best Answer:Once you swap to a double basket, this will thread on the rocket and other ecm portafilters. However, while it threads on well, when tightend all the way, the spout may not align perpendicular with the portafilter handle. this makes tamping tricky as it will be crooked. I put a spring washer on mine to fix the prob and its perfect!
