Momcozy Duckbill Valve for M9 (2-Pack)

The duckbill valve is what creates the vacuum in your Momcozy M9. 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 M9 Mobile Flow wearable pump
• Restores lost suction and keeps milk flow steady
• Pack of 2 valves
• Soft, food-grade silicone; BPA-free
• Replace if suction drops or the silicone shows wear, roughly every three months
• Note: this is the M9 part — different from the M5 and M6 valves
