Flange Insert Compatible with Momcozy, bluefair BIOBOO and More 24mm Breast Pump Models

This product offers a range of models that can accommodate mothers with different nipple sizes. The "breast milk channel" on the cover of the breast pump can be adjusted to suit various nipple dimensions, thereby enhancing breastfeeding efficiency and increasing pumping capacity, while providing greater comfort for mothers during the process.

The Durceler 2 Piece 21mm flange inserts are compatible with a variety of popular breast pump brands, 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 21mm, providing a seamless fit. Additionally, they are compatible with Lansinoh and Freemie 25mm cups, reducing them to 21mm.

Seamless Compatibility for Optimal Milk Expression: The product is suitable for nipple diameters ranging from 18-20mm (after a pumping session) or a nipple base circumference of 50.24 - 56.52mm before a pumping session. This makes it a great solution for mothers with small nipples using large breast shields, as proper nipple tunnel fit is crucial for comfort and efficient milk output.

The inserts are compatible with a wide range of brands, including Spectra and Medela (Freestyle, Harmony, Sonata, and Swing-Maxi pumps), as well as other popular brands.

Replacement Guidance: It is recommended to replace 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.

Maintain Compatibility with Most Hands-Free Bras: The inserts can be used with most hands-free bra cups, including the original 24/25mm detachable shields. During operation, users may need to squeeze the insert slightly to ensure a perfect fit with the shield, achieving the desired effect.
