This replacement kit includes two duckbill-style valves and two silicone diaphragms (membranes) designed to maintain the suction integrity of the Mumflöw X2 wearable breast pump. As vital components in the closed-system design, they ensure efficient milk extraction by regulating airflow and pressure during pumping sessions.

PRODUCT FEATURES

• Complete Valve System:
