Although this basket is called a “53mm” basket for accurate tamper sizing, the actual measurement 53.5mm and so it is also referred to as a 54mm basket.
Fits:
Starbucks Barista
Via Venezia
ALL Saeco Semiautomatic Machine Portafilters
NOTE: This basket fits very tightly inside the pressurized portafilter. Over time, removing them from the portafilter for regular cleaning will loosen the clip that holds them so snugly and they will be easier to insert and remove.
