The Ameda Breast Flange reducing insert fits inside the standard 25 mm flange to reduce the diameter to 22.5 mm.
The breast flange is the funnel shaped piece that cups your breast.
A good fit is important! Make sure your breast flange is not too small or too large.
Using the wrong size will cause discomfort and reduce the effectiveness of your pump.
Sold individually - for double pumping purchase two inserts.
