GOCROWEEN Flange Inserts 13-21mm (14pc) for 24mm Shields – Compatible with Momcozy, Medela, Spectra & More

Adaptable sizing for a comfortable pumping experience

GOCROWEEN flange inserts are designed to convert a standard 24mm shield into a precise, personal fit. This 14-piece set covers seven sizes—13, 15, 17, 18, 19, 20, and 21mm—so you can tailor the seal to your body, pumping rhythm, and daily routine without changing your shield.

Flexible sizing that respects your comfort

• Seven size options (13, 15, 17, 18, 19, 20, 21mm) to match your 24mm shield for a nuanced fit.
• Made from BPA-free, food-grade silicone with soft edges that feel gentle against the skin.
• Broad compatibility with popular pumps, including Momcozy S12 Pro/S9 Pro/S9/S10/S12, plus many 24–25mm models from other brands.
• Helps create a steady seal that can support a comfortable pumping rhythm, reducing the need to adjust constantly.
• Lubrication tip: a small amount of coconut oil or nipple butter can ease attachment and reduce friction.

Usage tips and care

Choose the right size by observing how the nipple sits during pumping. For best results, replace inserts every 1–2 months to maintain fit and hygiene. Rinse with warm water, use mild soap, and air-dry before storage.

Material safety and maintenance

• BPA-free, food-grade silicone that’s easy to clean and store.
• Keep inserts dry and clean between sessions to prevent residue buildup.

Real-world scenarios

Whether you’re adjusting to a new shield or balancing pumping with daily activities, these inserts offer a practical way to fine-tune fit. The right size can help you maintain comfort over longer sessions and simplify post-pump cleanup.
