18mm Flange Insert Compatible with Momcozy, bluefair BIOBOO, Bellababy, and More Breast Pumps

This product offers a variety of models, enabling mothers with different nipple sizes to find the suitable "breast milk channel" on the cover of the breast pump. This feature helps to improve breastfeeding efficiency, increase pumping capacity, and provide a more comfortable experience for mothers during the process.

The Durceler 2 Piece 18mm flange inserts are compatible with a wide range of breast pump models, including Momcozy S9 S10 S12 Pro, bluefair, BIOBOO, S18 S21 S23 Wearable Breast Pump, Medela, Spectra S1 S2, TSRETE, FEISIKE, Rainyb, Bellababy MiniO, NCVI, kmaier, MomMed, NaNaLazy, NIRGU, Onlyeah, MomWills, Motif Luna, and Amada MYA. These inserts can reduce the 24mm shield nipple tunnel down to 18mm, making them compatible with Lansinoh and Freemie 25mm cups as well.

The product ensures seamless compatibility for optimal milk expression. It is suitable for mothers with a nipple diameter of 16-17mm (after a pumping session) or a nipple base circumference of 43.96 - 47.10mm (before a pumping session). This solution is particularly beneficial for small-nippled mothers using large breast shields, as proper nipple tunnel fit is essential for comfort and efficient milk output. The product is compatible with a variety of popular breast pump brands, including Spectra and Medela (Freestyle, Harmony, Sonata, and Swing-Maxi pumps).

The replacement guidance suggests replacing the inserts every 4-12 weeks, depending on the duration and frequency of each pumping session. The inserts are durable, clear, and comfortable, made of BPA-free silicone material.

The product maintains compatibility with most hands-free bras. Mothers can use most hands-free bra cups with the original 24/25mm detachable shields, with the insert placed inside. During operation, users may need to squeeze the insert slightly to ensure a perfect fit with the shield, achieving the desired effect.
