Frequently Asked Questions

Q: Are these silicone flange inserts compatible with my Momcozy or Medela breast pump?

A: Yes! These silicone flange inserts are designed to be widely compatible with most major breast pump brands, including Momcozy (M5, M6, M9, S12 Pro, V1 Pro, V2 Pro), Medela, Spectra, Eufy E10/S1/S1 Pro, and many more. They fit into standard 24mm pump flanges and reduce the tunnel to 17mm, 19mm, or 21mm.

Q: How do I know which insert size is right for me?

A: The correct flange insert size is typically based on your nipple diameter. The right fit means your nipple moves freely in the tunnel without excess areola being pulled in. Your ideal size can also change during different breastfeeding stages, so it's a good idea to try multiple sizes — this 6-pack includes 17mm, 19mm, and 21mm to help you find the best fit.

Q: How often should I replace my silicone flange inserts?

A: It is recommended to replace your flange inserts every 1–2 months, or sooner if you notice any wear, tearing, or changes in the silicone material. Regular replacement helps maintain hygiene and ensures consistent pumping efficiency.

Q: Are these flange inserts safe for my baby?

A: Absolutely. These inserts are made from food-grade, BPA-free frosted transparent silicone with no high-concern chemicals, making them safe for both nursing parents and babies. They are also sterilizer-safe and easy to clean after every use.
