Durceler 17mm Silicone Flange Inserts Compatible with Medela/for Spectra S1 S2 / Elvie / S18 S21 / Momcozy S9 S12/ TSRETE 24mm Breast Pump Shields or Freemie 25mm; Reduce Tunnel Down to 17mm

I purchased these flange inserts for my pump parts that came with enormous flanges. You will need flange inserts for almost any pump you have. These fit well and are made of thick, quality silicone. The price was a little steep but it was worth the comfort while pumping. An essential for pumping mamas.

Hay mejores, este silicon irrita un poco y es necesario usarlos con lubricante

They do just what they claim.

Such a simple and easy fix to the huge falange sizes that come standard on pumps. Way easier & cheaper than having to buy your right size falange piece. Used it multiple times a day for months & put in dishwasher with zero problems

These inserts worked perfectly in my spectra pump. They are good quality and will last over the long run. However, I ended up buying flanges in my size to replace the flanges that the pump came with so I no longer have any need for these. I like being able to just use the flange so that I can see through to make sure there is no rubbing. The insert makes it very difficult to see through to make sure it is lined up correctly.
