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’ve said it before and I’ll say it again, Maymom has saved the day when I has come to breastfeeding my baby! I have ordered multiple pump parts, shields and inserts. Great quality, great value!

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 :)

Fits great on spectra pumps. No leaks

I pumped for a year with the wrong sized flanges because I was too cheap to buy the correct size. Totally regret that! No discomfort pumping with these vs when I was using 24 mm ones. Can’t really tell if they helped increase production but it certainly didn’t decrease it!! It is weird how smaller flanges are more expensive but oh well. Worth it!

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

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!

These fit my Spectra S1 perfectly.

I purchased these flanges after using a sizing tool on Pumpables website. Many people are encouraged to use a flange that’s too large, which can lead to pain and low milk retrieval. This was my case. I sized down to a 17 mm. These flanges are as advertised. I think there was one low review stating there was no suction. This is just for the flanges. It does not include the white cap that funnels the milk from flange to bottle. You won’t get suction without them. I just placed the original ones that came with the pump on these and everything is working fine.

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!!

I wish I would’ve purchased these sooner for my spectra. Love that you can get more sizes than spectra offers
