Momcozy Original S9 Pro/S12 Pro Replacement Full Set Collector Cup

The Momcozy Full Set Collector Cup for S9 and S12 pumps, available from Fed is Best, refreshes the milk-collection components that sit inside your hands-free pump. Wearable systems rely on well-fitting silicone and plastic parts to maintain suction and comfort. With frequent washing, sterilising and daily handling, these parts eventually wear down. A replacement set helps your pump work efficiently and supports safe milk storage.

When to replace collector cups

• Silicone feels stiff, cloudy or warped.
• Output drops unexpectedly despite routine consistency.
• You notice small leaks or weakening suction.
• You want a second clean set for work or travel.

Use-cases where a spare set helps

Many families find expressing easier when they keep two collector cup sets at home: one for immediate use and one drying after washing. This reduces pumping interruptions and helps maintain hygiene during busy routines.

Compatibility

This set is designed for the Momcozy S9 Pro and S12/S12 Pro wearable pumps.

Cleaning and sterilising

Disassemble all milk-contact parts and wash after each session using warm, soapy water. Rinse thoroughly and let everything air-dry. Sterilise regularly, especially for newborns or early pumping stages.

Why buy from Fed is Best
