The Momcozy M5 Full Set Collector Cup, available from Fed is Best, replaces the milk-collection unit for your M5 wearable pump. Frequent washing, sterilising and daily use naturally wear down silicone components. When these parts degrade, suction may weaken or the pump may feel less comfortable. Replacing the collector cup restores proper performance and supports safer milk handling.

Why replacement matters

The collector cup is central to creating an effective pumping seal. A damaged or ageing cup can lead to leaks, reduced output or discomfort during sessions. Swapping out worn components helps keep your pump functioning as consistently as possible.

Ideal for everyday pumping

Pumping parents often wash parts multiple times a day. Having an additional set of collector cups means you can rotate between washes, reducing downtime and helping you stay on track with your pumping schedule.

Compatibility

This set is compatible exclusively with the Momcozy M5 wearable pump. It fits securely into the existing motor and flange design, making replacement straightforward.

Cleaning and storage

Always disassemble and wash components that come into contact with milk. Allow parts to dry completely before storing or reassembling. Inspect the silicone regularly for stiffness, discolouration or fine cracks that indicate it is time for another replacement.

Supporting your feeding journey

Using well-maintained pumping equipment helps protect comfort and output. Fed is Best offers accessories for cleaning, storage and bra support so you can create a reliable system that suits your lifestyle.
