Momcozy Duckbill Valve for M5 (4-Pack)

The duckbill valve is what creates the vacuum in your Momcozy M5. It is the first part to soften with use, and a tired valve is the usual reason suction feels weaker — swapping in a fresh one restores it in seconds.

• Replacement duckbill valves for the Momcozy M5 and M5 Smart
• Restores lost suction and keeps milk flow steady
• Pack of 4 valves
• Soft, food-grade silicone; BPA-free
• Replace if suction drops or the silicone shows wear, roughly every three months
• Note: this is the M5 part — different from the M6 and M9 valves
