GOCROWEEN Flange Inserts 13–21mm | 10-Piece Set for 24mm Shields – Compatible with Momcozy, Medela, Spectra, Bellababy and More

GOCROWEEN Flange Inserts: Dial in the 24mm Shield Fit

Choosing the right flange size is a key part of a comfortable pumping session. The GOCROWEEN flange inserts are designed to work with most 24mm shields and a wide range of brands, including Momcozy, Medela, Spectra, and more. This 10-piece set covers five sizes—13, 15, 17, 19, and 21 mm—with two inserts of each size, giving you options to refine the seal without buying multiple complete kits.

Design and materials

The inserts use transparent silicone that feels soft and flexible while maintaining a reliable seal. BPA-free composition means everyday use with confidence. The clear silicone lets you inspect the fit at a glance, helping you adjust as needed during a pumping session.

What makes them useful

• Compatibility across many popular 24mm shield brands, so you can mix and match without new parts
• Five sizes to dial in the best fit for varying nipple sizes and day-to-day changes
• Two inserts of each size help you quickly compare different fits
• Transparent silicone material is BPA-free for everyday comfort and confidence
• Note: designed for 24mm shields only; cannot be used with 27mm shields

How to use and care

• Test two inserts at a time to identify the most comfortable combination
• Apply a small amount of coconut oil or nipple butter to reduce friction during insertion
• Clean with mild soap after use and let air-dry completely before storing
• Keep in a cool, dry place to maintain silicone integrity

Packing a flexible sizing solution can be particularly helpful during busy days, travel, or sessions where you notice subtle changes in fit. Instead of replacing an entire shield, you can fine-tune with inserts to sustain a comfortable seal and steady pumping rhythm.
