Did you know the duckbill valve is the heart of your breast pump’s suction? This little silicone piece creates the seal required to express milk efficiently. If you’ve noticed a sudden drop in suction or milk output, a worn-out or damaged valve is often the main culprit.

This is the ncvi wearable pump’s replacement duckbill valve.
