15mm Flange Insert Compatible with Various Breast Pumps

This product offers a range of models designed to adjust the size of the "breast milk channel" on the breast pump cover, catering to mothers with different nipple sizes. This customization helps enhance breastfeeding efficiency, increase pumping capacity, and improve overall comfort during the feeding process. The Durceler 2 Piece 15mm flange inserts are compatible with various wearable breast pumps such as Momcozy S9 S10 S12 Pro, bluefair, BIOBOO, S18 S21 S23, as well as Medela and Spectra S1 S2 pumps, among others.

These inserts are specifically designed to reduce the nipple tunnel from 24mm to 15mm, allowing for optimal milk expression. They can also be used with Lansinoh and Freemie 25mm cups to adjust them to 15mm. Ideal for mothers with smaller nipples using larger breast shields, ensuring a proper nipple tunnel fit is crucial for both comfort and efficient milk output.

Regular replacement is recommended every 4-12 weeks, depending on the duration and frequency of pumping sessions. These durable, clear inserts are made of BPA-free silicone material, ensuring safety and comfort.

Maintaining compatibility with most handsfree bras, these inserts can be used with original 24/25mm detachable shields. Simply squeeze slightly during use to ensure the insert fits snugly with the shield for optimal performance. Perfect for use with Spectra, Medela, and other major pump brands.
