This complete collector cup set is designed specifically for compatibility with the Momcozy M5 breast pump, offering a comprehensive solution for milk collection and flange fitting. The set includes two 24mm collector cups along with ten flange inserts sized at 13mm, 15mm, 17mm, 19mm, and 21mm (two of each), allowing users to achieve a precise and comfortable seal based on individual nipple dimensions. The two 24mm flanges are also included, providing an additional direct-fit option. The kit comes with two duckbill valves and two diaphragms, ensuring reliable milk flow and maintaining hygiene during use. The collector cups are made from food-grade, BPA-free materials that are durable and easy to clean. The flange inserts feature a soft, flexible silicone construction that adapts to the breast shape, minimizing discomfort during pumping sessions. The duckbill valves are designed to open and close efficiently, preventing backflow and maintaining vacuum pressure for consistent milk expression. The diaphragms serve as a protective barrier, reducing the risk of milk entering the pump tubing and simplifying maintenance. The set is an affordable alternative to purchasing individual components separately, offering substantial savings without compromising on fit or function. The included sizes cover a wide range of nipple diameters, making this kit suitable for many users seeking a customized pumping experience. The materials are resistant to wear and tearing, extending the lifespan of the accessories while maintaining performance through frequent use and sterilization cycles. The overall design prioritizes ease of assembly and disassembly, facilitating quick cleaning and drying between uses. The collector cups have a clear visibility window, allowing users to monitor milk volume during pumping. The inserts are interchangeable without tools, enabling fast size changes if needed. This set supports the Momcozy M5 pump’s original function while expanding compatibility for different body types. For those seeking a cost-effective way to upgrade or replace their current collection components, this bundle delivers great value. It combines essential replacements for valves and diaphragms, ensuring the pump remains in optimal working condition. The generous number of inserts means users can share the set among multiple pumpers or keep backups for emergencies.

The kit is a practical investment for enhancing the pumping experience with a reliable, comfortable fit.
