S9, S12 Pro | Replacement Diaphragm & Valve

Some breast pump accessories do need replacing regularly to maintain performance. If you notice your pump seems to have lost suction, the first thing you should do is check your parts and inspect for wear, fraying or stretching, and replace if needed.

The duckbill valve allows milk to drain into the collection cup, while the diaphragm aids in sealing the pump to prevent milk leakage.

In order to maintain the optimal suction, it is recommended to replace washable accessories every 3 months.

Note:
DO NOT microwave-sterilize to prevent parts from melting. DO NOT expose to temperatures exceeding 110°C.
