One Full Set Collector Cup Compatible with Momcozy M5 - Replacement

In this review of the One Full Set Collector Cup replacement kit, the focus is on owners of the Momcozy M5 wearable breast pump who need a reliable parts refresh. The kit replaces the milk collector cup, 24mm double-sealed flange, silicone diaphragm and duckbill valve, and the biggest reason to consider it is practicality: it restores pump performance quickly and cheaply without buying a new unit. The reviewer found the kit useful for routine maintenance and for extending the usable life of a Momcozy M5 pump, with clear advantages in anti-backflow design and food-grade materials.

Key Features

• Complete replacement set: Includes one milk collector cup, one 24mm double-sealed flange, one silicone diaphragm and one duckbill valve so users get all primary wearable pump parts in one purchase.
• Designed for Momcozy M5: Purpose-made compatibility with the Momcozy M5 wearable breast pump to restore the original fit and function without mixing parts from other models.
• Anti-backflow protection: The silicone diaphragm incorporates an anti-backflow design that reduces milk reflux and helps keep pump components cleaner over time.
• Anti-overflow valve: The duckbill valve is shaped to direct milk upward only, minimizing spills and contamination during collection.
• Food-grade materials: Made from BPA-free silicone and plastic for a soft, odor-free experience and safe contact with expressed milk.
• Easy to clean: Parts can be washed in warm soapy water and sterilized by boiling or steam for 5 to 10 minutes to maintain hygiene.

Who It's For

This replacement kit is best for parents who already own a Momcozy M5 wearable breast pump and need a full set of collector components to replace worn or lost parts. It is useful for anyone prioritizing hygiene and anti-backflow protection to maintain consistent suction and milk safety.

It is not for owners of other pump brands or model lines, and it is not an original manufacturer accessory; buyers who require guaranteed OEM parts or who need parts for a different pump should look elsewhere.
