Momcozy Original Parts are FSA/HSA eligible. Suggest using the FSA/HSA card at checkout.
Diaphragm - Maintains Suction Operation
To stay sealed and prevent milk leakage. After the process is upgraded, the surface texture process is added to further improve the installation sealing and suction stability.
Duckbill Valve - Drainage without Backflow
For draining milk to the bottom of the container and no milk backflow. After the process upgrade, the surface texture process is added, which further improves the installation sealing and suction stability.
Comfort & Professional
The rim is specially designed for soft breasts, easily and quickly reducing the large flange to a custom size, momcozy insert sizes are 15/17/19/21mm.
No Backflow of Milk
An additional collar around the insert ensures that milk cannot flow back into the space between the insert and the flange. Provides a complete seal for improved suction.
Only Compatible with Momcozy S9 Pro/S12 Pro, NOT Compatible with S9/12, etc.
Use a Ruler or Measuring Card
Place the bottom of the nipple perpendicular to the ruler or nipple measure tool card (included in the package of S9 Pro/S12 Pro).
Determine Your Size
Use a size chart for guidance on the proper size for the fit. The size of the flange insert is very important for comfortable and efficient pumping. If your nipple rubs or feels squeezed in the flange channel, it is an unsuitable flange size and you need to replace the right size flange/insert.

I wanted to get an extra set for backup. I don’t feel like the seal is as good as the one directly from momcozy. It leaks just a bit.
Love how close to the ground it is!!

These are the exact same as the original set that comes with the wearables and so happy I got them for a quarter of the price. You can’t tell the original from this product and is a perfect replacement or addition!

You CAN use these with a spectra! Was looking for wearable cups to use with my spectra while I work and saw mixed reviews about the spectra brand cups. Thought I’d give these a try and hoped for the best. They’re great! The tubes are a liiittle tight on the openings but it works.

I bought these extra breast pumping parts to keep in rotation, and it has been such a time-saver! Instead of constantly washing and reusing the same set, I now have a backup ready to go. It’s especially helpful for those late-night pumps when you don’t want to worry about cleaning right away.They also recommend replacing accessories every so often, so having extras on hand is a great idea. These parts fit my breast pump perfectly and have been super convenient to have in rotation. Highly recommend for any pumping mom!

This is a perfect fit for the momcozy S9 and a great alternative to buying a whole new pump if you lost just one piece.

These are great. I used them for many months. (Remember you need to replace the duck bills & suction every 90 days of use)I will say they didn’t have the lip that the ones that came with the breast pump.
