Flange Inserts 10PCS 13/15/17/19/21mm for Momcozy S12 Pro/M5/S9 Pro Hands-Free Breast Pump

Attention: Flange Inserts in sizes 13/15/17/19/21mm are only compatible with 24mm Shields/Flanges, not with 27mm Shields/Flanges or other sizes. To reduce friction and ease usability, consider using coconut oil or nipple butter. These inserts are designed for use with Momcozy S12 Pro/S9 Pro/S12/S9 Hands-Free Breast Pump, as well as with brands like Medela, Spectra, Elvie, Willow, and more.

If you're uncertain about the best size for your nipple, we recommend our Flange Inserts 13/15/17/19/21mm 10-piece set, which includes sizes suitable for most nipples under 24mm. This set also includes two inserts that can be used simultaneously. The JIMOWANG Flange Inserts 13/15/17/19/21mm 10pc set contains two of each size (5 sizes in total) for finding the right fit for your nipples.

You can use at least two flange inserts simultaneously for optimal function. These inserts are compatible with Electric Breast Pump 24mm Shields/Flanges from various brands. Suitable for S9/S10/S12 Wearable Breast Pump cups from Momcozy, TSRETE, kmaier, and others.

These replacement parts eliminate the need for trial and error in finding the correct nipple size. Many mothers have nipples of different sizes or experience changes in size over time. For nipples smaller than 24mm, we offer a convenient set that suits your needs.

Our Flange Inserts are made of food-grade silicone and are BPA free, ensuring easy maintenance and cleaning. Choose the appropriate insert size for your nipple comfort and optimal pump performance.
