2X 17 mm Maymom Wide Neck Pump Parts Compatible with Spectra S1/S2 Pumps; Incl Wide Mouth Flanges; Not Original Spectra Flange; Replaces Spectra Shield (Two Small Flanges)

Thank you for saving my milk supply! I was so nervous it was diminishing and all it took was finding the right flange size! Great quality, fits perfectly on my spectra 2, maymom is the best!! thank you for accommodating those of us who are petitely endowed :)

Once I got properly sized and ordered these pumping became a lot less stressful! They fit on my Spectra perfectly and have worked without a hitch since they arrived!

Wonderful product to get the right size!

Got the 17mm flanges to use with glass bottles that are compatible with spectra 2 pumps. The flanges are awesome and finally fit for the best pumping sessions possible, but more importantly no more painful pulling/lack of suction! The flanges dont fit tightly on the Matys brand glass bottles I got but as long as you dont move around much, its no biggie. Its awesome to have no more painful pinching on one of the most sensitive areas of the body, especially how often every momma has to pump!

Fits great on spectra pumps. No leaks

These flanges are great! I am collecting much more milk now that I have to correct size for my pump! My only wish is that I wouldn’t leak a bit out of the shield

After trying to pump with my Spectra S2 pump for months I finally discovered the standard flanges were way too big. I was super discouraged when I found out spectra didn’t offer anything smaller than 21. But these are perfect! They attach wonderfully with my pump, hoses and valve.

These fit on my spectra no problem! Wish I’d bought them earlier to avoid some of the problems I had pumping

I was hoping to increase my supply with a smaller flange but it did not help. However the flange works just like the Spectra one. No issues with the flange.

I needed a smaller flange size but unfortunately Spectra did not make 17mm. These work PERFECTLY with my Spectra S1 and have been so much more comfortable than the 24mm flanges the pump came with.
