21mm Flange Insert for Momcozy S9 S10 S12 Pro and Other Compatible Pumps

This product features a range of models designed to adjust the size of the "breast milk channel" on the breast pump cover. This adaptability caters to mothers with varying nipple sizes, enhancing breastfeeding efficiency and pumping capacity while ensuring a more comfortable experience for mothers during the breastfeeding process.

The Durceler 2 Piece 21mm flange inserts are compatible with various breast pump models including Momcozy S9, S10, S12 Pro, Bluefair, BIOBOO, S18, S21, S23 Wearable Breast Pump, as well as Medela and Spectra models such as S1 and S2, along with TSRETE, FEISIKE, Rainyb, Bellababy MiniO, NCVI, Kmaier, MomMed, NaNaLazy, NIRGU, Onlyeah, MomWills, Motif Luna, and Amada MYA. These inserts provide a solution to reduce the standard 24mm shield nipple tunnel down to 21mm, and they are also suitable for Lansinoh and Freemie 25mm cups, effectively cutting them down to 21mm as well.

This product guarantees seamless compatibility for optimal milk expression. It is designed for nipple diameters of 18-20mm after a pumping session, or the circumference of the nipple base should be measured to be between 50.24 - 56.52mm before pumping. This feature is an excellent solution for mothers with smaller nipples using larger breast shields. A proper fit for the nipple tunnel is crucial for both comfort and efficient milk output. Additionally, the inserts are compatible with a range of brands including Spectra and Medela (Freestyle, Harmony, Sonata, and Swing-Maxi pumps) among others.

To maintain the effectiveness of the inserts, it is recommended to replace them every 4 to 12 weeks, depending on how often and how long each pumping session lasts. Made from durable, clear silicone material, these inserts are BPA-free and designed for comfort.

Moreover, these inserts maintain compatibility with most hands-free bras. You can utilize the original 24/25mm detachable shields with the inserts in place. It’s important to note that during operation, a slight squeeze is required to ensure the insert fits snugly with the shield, achieving the desired performance.

In summary, this innovative product is a thoughtful solution for mothers looking for a tailored pumping experience. By adjusting the nipple tunnel size, it not only caters to individual comfort but also enhances the overall efficiency of breast pumping. The versatility and compatibility of the Durceler flange inserts with numerous breast pump brands make it an essential accessory for modern mothers. Whether facing challenges with sizing or looking to improve pumping comfort and output, these inserts provide a significant advantage in the breastfeeding journey.
