Blind Filter Basket - Backflush Disc RubberBy Rancilio
Most commercial semi-automatics require backflushing on a daily basis to get rid of coffee residue and build-up that can change the taste of your espresso. This rubber disc is for use on machines with a 3-way solenoid valve. Simply place it in your portafilter along with backflush cleaner, and begin the process that should be detailed in your machine’s manual.
Compatible with 58mm portafilters.
