About this item

Product details

These Momcozy diaphragm + valves are suitable for use with any following breast pump: Momcozy S9 Pro and S12 Pro wearable breast pump. The diaphragm is used to help the breast pump maintain the seal to prevent milk leakage. The duckbill valve can be used to drain milk to the bottom of the container. The general service life of the duckbill valve is about 2-3 months. If it is found that suction is not good, it will reverse flow, and milk doesn't go into the collector, it is generally that the valve is not closed well and needs to be replaced.
