Circular Grouphead Cleaning Brush (56-58 mm.)

This brush has nylon bristles, and was made to clean the group head of your espresso machine. Grounds will get stuck on the outside of the grouphead. These will cause 2 problems: 1) they will prevent you from getting a good seal when you lock in the group, and you'll get pressure leakage when pulling a shot, and 2) you will wear down your gaskets much faster. This brush will solve both problems. Well worth its price!
