Adapter Ring PRO-Classic

The machining on this ring is precise, so it seats snugly into the portafilter base without any wobble. Swapping it out for the PRO Brew Head took less than a minute, and now the extraction channel is perfectly aligned.

The fit is now flawless after swapping this in; the ring locks into the portafilter base exactly as it should, and swapping back to the PRO Brew Head takes seconds. Took a bit to align the threads on first install, but once seated, it hasn't budged.

The ring seats into the portafilter base with a satisfying click, and swapping it out to switch to the PRO Brew Head took me all of ten seconds. Feels solid in the hand, no wobble once it’s locked in.
