BDICOVE 4-Pack M9 Replacement Diaphragms & Duckbill Valves for Momcozy Upgraded Mobile Flow M9 (Not Original Parts)

BDICOVE Replacement Parts for Momcozy Upgraded Mobile Flow M9

Keep your pumping routine smooth with the BDICOVE 4-pack, featuring 2x double-layed diaphragms and 2x duckbill valves. Engineered to fit the Momcozy Upgraded Mobile Flow M9, this kit prioritizes compatibility, durability, and ease of use without claiming to be an original part.

The diaphragms use a thoughtful two-layer design—a silicone layer paired with a plastic layer—to help maintain consistent suction and provide reliable sealing during sessions. The duckbill valves are one-piece by design, where the plastic layer and valve components are permanently joined to simplify assembly and promote milk drainage toward the bottle while reducing backflow.

Care, maintenance, and real-world tips

After each use, wash with warm soapy water and rinse well. Sanitize by boiling or steaming at about 100°C. If suction seems reduced, consider replacing parts; manufacturers often recommend periodic replacement every ~3 months for optimal performance.

In busy mornings or during night-time pumping, these replacements offer practical, ready-to-use components to keep your routine flowing smoothly and with less hassle, while still aligning with your device’s original design intent.
