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)

✫ The only differences between these generic spectra flanges and the real Spectra flanges are cost and diameter. ✫ I thought I had large nipples, but it turns out theyre significantly smaller than the standard 24/25mm flanges included with every dang pump (Medela, Spectra, and Ameda). ✫ If youre having trouble with pain and output, I implore you to grab a ruler and measure your nipple diameter BEFORE pumping. If youre areola is being pulled into the flange during pumping, its too big. ✫ Using a caliper (the tool jewelers use to measure diameter), I found I was 14.5mm, so like 10mm less than the standard flange. Since switching to the 17mm flange, my output has increased and pain is non existent.

These are a really nice quality. I love that these tighten well onto spectra bottles. Its nice and tight with plenty of threads so that it actually grips. The flanges are deep and angled down, which is nice. I definitely appreciate the smaller size, too!

I brought this product for my BestFriend to use and when we got the package it was open and had been used, there was somebody’s breast milk inside the tube pump part, it was gross not I have to send it back and I’m waiting for a replacement

I ordered these and they came used in a ziplock bag with dried white milk remnants. Absolutely disgusting. Nowhere did it mention sending used parts. I expected brand new from a sealed bag.

Properly sized flanges make a world of difference to comfort and output. Ive tried Pumpin Pals, silicone inserts, and finally figured out the right size for me. Turns out regular plastic flanges work just fine when its the right size. These work with my Spectra perfectly and Im pumping faster than ever.

I really like that it worked with my spectra s2

Works great

I have gotten several knockoff flanges as Im trying to find my best fit. My only complaint is at least I cannot personally see any numbers indicating the size they are. I can figure it out, but I have to closely compare. I wish it were just written on there. Otherwise great product

I liked that the carry this size since most default to 19 or 24 for the longest time i couldn’t figure out it was too big.

This is the brand my lactation consultant recommended, great quality product so far. Had no idea knowing nipple size is so crucial to take into account while pumping - turns out Im 17mm, much smaller than what breast pumps come with by default. Tell every mom you know! The standard flange size is TOO LARGE for most women, its not average at all - which can be detrimental to milk supply.
