Refresh your wearable breastpump with the Gotocut 12 Count Duckbill Valve Silicone Diaphragm Replacement Kit. Designed for NaNaLazy Momcozy S9 Pro and S12 Pro models, this gender-neutral kit swaps in durable silicone parts that help restore suction and streamline milk flow.

Why replacement matters

Over time, wear on the valve and diaphragm can affect how the pump draws milk and directs flow. A fresh set helps reestablish a steady suction and clean milk-path direction, which many parents appreciate during busy days. This kit also serves as a dependable backup for home, work, or travel, so you have ready replacements when schedules shift.
