Premium materials you can rely on

Crafted from food-grade silicone, these diaphragms and duckbill valves are BPA-free, soft to the touch, and odorless. The silicone formulation is designed to minimize leaking when properly seated, supporting a comfortable pumping experience and preserving milk-collection reliability.

Clean, simple maintenance

Cleaning is quick and straightforward: the valves are compatible with standard sanitation methods, including steam and boiling water. After each session, a gentle rinse and a brief boil or steam sanitize can help keep parts fresh and ready for the next use.

How often to replace and why

To help maintain pump performance, NCVI recommends replacing duckbill valves every 4–12 weeks, depending on usage and cleaning frequency. Regular replacement supports consistent suction and reduces the chance of material fatigue.

Quality you can trust

Independent labs have tested these valves for quality and safety, reflecting NCVI’s commitment to reliable replacement parts. The valves are designed to work with NCVI wearable pumps and to integrate with the overall system with minimal fuss.
