21 mm Flange for Momcozy M5 Flanges

The 21 mm flange for Momcozy M5 flanges is a replacement accessory designed for the Momcozy M5 portable pump. The 21 mm flange helps achieve a better fit when a smaller diameter is required, ensuring comfort and more effective pumping.

• Better fit for nipples with small diameter, reducing friction on the flange.
• Helps maintain seal and suction when the regular size does not fit well.
• Useful spare accessory to avoid interrupting your pumping routine.
• Multi-piece packaging, convenient for daily use and rotation during cleaning.

Compatibility

The 21 mm flange is compatible with the Momcozy M5 pump and is specially designed for this model. For double pumping (two units), it is recommended to have pumps for both sides to ensure similar settings.

How to Choose the Right Size

The correct size matters for both comfort and milk flow. During pumping, the nipple should move freely inside the tube without being tight or causing friction. The 21 mm flange is a suitable choice when a smaller size than the regular flange is needed.

Maintenance

• Wash after each use with warm water and mild detergent, then rinse thoroughly.
• For sterilization, parts that come into contact with milk can be boiled for 5-10 minutes, then fully aired.
• Regularly check for signs of wear (deformation, cracks, seal failure) and replace as needed.
