Milk Expression Cup Kit - Breast Shield, Valve & Collector Assembly for Stacy Wearable Breast Pump | Replacement Parts

Key features:

- Breast shield (contoured for comfort and fit)
- Milk collector cup (clear, easy to see output)
- Valve assembly (creates the suction mechanism)
- Valve plate (regulates flow)
- Diaphragm (essential for pump function)

What's not included:

Motor, different flanges, or nipple size guide (sold separately)

Why it matters:

Whether you're dealing with wear and tear from frequent use or you need a fresh set for hygiene reasons, having a reliable replacement cup kit keeps your pumping journey uninterrupted. A functioning valve system is crucial for consistent suction and milk output.

Care instructions:

All parts are easy to clean and sterilise. Use warm soapy water for cleaning and sterilise only once a day or once in 2 days.

When to replace:

Replace your cup kit every 2-3 months, or sooner if you notice a sudden drop in suction or unexplained low supply (beyond heavy pump use). If you're exclusively pumping with Stacy, definitely plan for regular replacements to maintain optimal performance.
