Silicone Bellow for Single-Dose Grinders

Two-unit pack of functional silicone bellows intended for use with Express-brand single-dose espresso grinders. Material: food-grade silicone (termed 'silica gel' in original listing, consistent with UK/EU terminology for medical- and food-grade silicone elastomers). No batteries or electronics — fully mechanical operation via hand compression. Locking ring ensures stable positioning on hopper base. Generates brief, focused airflow to clear residual grounds from critical grinding zones. Validated compatibility includes Express, Touch Impress, Smart Grinder Pro, Smart Grinder, Dose Control, Dose Control Pro, and Pro. Safe for top-rack dishwasher use; air drying preserves longevity. Retains flexibility and sealing performance after prolonged exposure to coffee oils and ambient humidity.
