M5, 6, 9 - Full Set Replacement Collector Cup

The Momcozy Collector Cup Full Set offers a complete replacement for the milk-collection chamber of your M5/6/9 wearable pump. Over time, regular washing and sterilizing can cause silicone and plastic parts to degrade; affecting suction, comfort and reliability. This refreshing set ensures your pump performs as intended and helps maintain hygienic milk handling. 

What's included

1 x Milk collector
1 x Diaphragm
1 x Duckbill valve
1 x Flange 24mm

When to replace

Wearable pumps depend on a well-sealed collector cup to create suction and store milk securely. If the material becomes stiff, cloudy or cracked, you may notice lower output, discomfort or leaks. Replacing the cup restores a tighter seal and helps your pump work closer to its original performance.

Maximize your pumping routine

Having spare collector cups on hand can make pumping easier, especially on busy days. Parents often keep one set ready for immediate use while another dries after washing. Momcozy offers accessories that complement the M5/6/9 system, so that you can build a practical kit that fits your lifestyle.
