These items are after market parts made by Maymom to replace your Ameda Flange and Ameda white valve/duckbill. It is well known that choosing the correct size of flange (breastshield) is important to achieve comfortable breastmilk pumping. While Ameda provide CustomFit flanges, some of the sizes are achieved using inserts which are not easy to use, and tend to leak air easily.
