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)

I got these for my Motif Luna pump because some comments said these are compatible, and the documentation in the bag says they’re compatible too, but they’re not. The back flow dial things don’t fit in the flange, the spot on the flange where you insert them is too short and they don’t fit at all. Really disappointed because I can’t find any 17mm that fit anywhere.

This flange ended up being a little too small for me. Still a good flange though! I love that this company offers more sizes than spectra! I just wish the company offered to sell this size as an individual flange instead of a pair to test the size without spending as much money

Works great

I was pumping using a size 24mm for 2-ish months before realizing I was really a size 17mm. The hospital I went to only carried size 24mm and 28mm flanges, so I was told I was a size 24mm. Dont trust them! Use a nipple ruler and find out your true size!!! Life saver! Pumping with ease now!

The subject says it all. One of the two pack leaks from the connection to the Spectra bottle. I couldn’t figure out what was happening at first but lost a bunch of milk because of this. I will buy again because I can’t find the size I need elsewhere but am disappointed.

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!

I really like that it worked with my spectra s2

This sizing fit much better for me than the standard sizings. It also works perfect with my spectra pump. Wouldn’t even know the difference between the spectra flanges and these if it wasn’t for the brand names on the flanges.

Spectra doesnt make smaller flange sizes, so I was thrilled to find this size from maymom. The quality is comparable to the original Spectra flanges. The smaller size fits so much better and makes pumping comfortable.

Highly recommend that you measure yourself before buying. I was in pain because I had been using 28 and 30mm turns out I was 17mm!!
