afontoto 6-Pack Duckbill Valve & 4-Pack Diaphragm for Momcozy S12Pro/S9Pro/S12/S9 Wearable Pump – Replacement Parts

Designed for the Momcozy S12Pro/S9Pro/S12/S9 wearable pumps, this afontoto replacement parts kit brings together two essentials in one convenient set. The six duckbill valves guide milk toward the container while helping prevent backflow, and the four silicone diaphragms support a reliable seal during pumping. In everyday use, you’ll notice smooth valve action at the milk path and secure diaphragm contact against the pump flange, which helps minimize leaks between sessions.
