Momcozy M6 Wearable Breast Pump Replacement Parts – Flanges, Valves, Diaphragms, Inserts

These are genuine Momcozy replacement parts for the Momcozy Mobile Style / M6 wearable, hands-free breast pump. The soft parts of any pump wear over time — and worn valves are the usual reason a pump seems to lose suction — so keeping fresh diaphragms, duckbills, flanges and inserts on hand keeps your M6 pumping at full strength.

Choose exactly the part you need from the dropdown: the complete Overall set (2 diaphragms, 4 duckbill valves, a 24 mm flange and a milk collector), individual flanges with collectors in 24 mm or 27 mm, flange inserts to size down to 15/17/19/21 mm, or spare duckbills, diaphragms and a flange cover. Momcozy advises replacing diaphragms and duckbills every 3 months, and flanges every 6 months.
