GOCROWEEN Flange Inserts 13–21mm (14pc) – 24mm Shield Compatibility for Momcozy, Medela, Spectra & More

Overview

Meet the GOCROWEEN Flange Inserts, a 14-piece silicone set crafted to adapt 24mm shield systems across a range of popular breast pumps. The sizes span 13, 15, 17, 18, 19, 20, and 21 mm, giving you multiple options to tailor the shield to your routine. This thoughtful selection is designed to help you explore comfort without guessing, while staying compatible with a broad ecosystem of pumps that use 24mm shields.

Why these inserts matter

Made from BPA-free, food-grade silicone, these inserts provide a soft, smooth surface that can feel gentler against skin and may contribute to a steadier, more relaxed pumping experience. For a smoother start or to ease insertion, a light touch of coconut oil or nipple balm can reduce friction and help the insert settle more comfortably.

Compatibility and versatility

Designed specifically for 24mm shields/flanges, the inserts align with popular models such as Momcozy S12 pro, S9 pro, S9, S10, and S12 wearable pumps. They also extend to other brands around 24–25mm (Freemie) and MISSAA hands-free pumps. Always verify shield size on your unit, since correct sizing supports comfort and effective workflow during pumping sessions.

Comfort, care, and replacement

The size you choose can influence comfort and pumping ease, so use the range to find your best fit. The silicone surface cleans easily and resists wear with proper care. Replacement is recommended every 1–2 months with regular use to help maintain a smooth surface and consistent fit.
