4pcs Flange Inserts 19mm for Momcozy, Elvie, Willow, Lansinoh, and Other 15mm-17mm Breast Pumps

The JIMOWANG flange insert, measuring 19mm*4, is designed to reduce the size of the 24mm shield nipple tunnel down to 19mm (not for 27mm shields). It's important to note that the size refers to the beginning of the tunnel, not the end. The size of your flange is crucial for comfort and pumping efficiency, so it's crucial to observe how your nipples look during a pumping session. During pumping, your nipples should not rub or feel squeezed inside the flange tunnel.

These flange inserts are compatible with a wide range of breast pumps, including Momcozy S12 Pro/S9 Pro/S12/S9 Hands-Free models. They also fit 24mm breast shields for various brands such as kmaier, TSRETE, Medela, Spectra, Elvie, Willow, Bellaaby, MomMed, MISSAA, Motif Luna, Ameda MYA, Ainsir, Phanpy, Lulia, NaNaLazy, Luxlady, kidzio, eulumap, Teexin, Fisroa, KISSBOBO, Goldeep, BIOBOO, Mumeasy, Nanawawa, TOVVILD, and CPPSLEE.

The JIMOWANG flange inserts are designed to maintain compatibility with most hands-free bras on the market. You can continue using most hands-free bras after installing these inserts inside the 24mm detachable shields.

Crafted from food-grade silicone, these flange inserts are BPA-free and easy to clean, ensuring a safe and hygienic pumping experience.

The JIMOWANG 10-pack flange inserts set includes two of each size (5 sizes in total: 13mm, 15mm, 17mm, 19mm, and 21mm), allowing you to find the correct size for your nipples. It's recommended to use at least two flange inserts simultaneously during pumping sessions. If you're unsure which size is best for you, we suggest purchasing the Flange Inserts 13/15/17/19/21mm 10-piece set to experiment and determine the optimal fit.
