Designed as reliable replacements for NCVI wearable breast pump systems, these duckbill valves are crafted to align with a range of popular models. The result is a practical option for keeping your pumping routine steady and on track, without unnecessary downtime.
These valves are sized and shaped to fit NCVI wearables that are commonly paired with models 8138, 8138-1, 8161, 8786, and 8122-3. A well-matched valve helps support a consistent milk flow during pumping sessions and reduces the need for frequent adjustments.
Four replacement valves in one set gives you ready options for daily use, travel, or sharing a pump with a partner. The design emphasizes a calm, uninterrupted routine by reducing the chance of leaks or wear mid-session.
After each use, rinse the valves and sanitize following your pump guidelines, then air dry completely. Inspect for wear and replace as needed to keep your setup dependable. In daily life, this pack suits busy mornings, overnight routines, and travel, offering flexibility without promising guaranteed results.
Note that while these valves are designed for compatibility and performance, outcomes can vary with usage, cleaning, and other factors. Treat them as dependable parts that support your pumping practices rather than a guaranteed improvement in every situation.
