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 ordered because I need the 17mm and that size is hard to find, but I just got these in and the tunnel is too short. I have elastic nipples so it doesnt work with the short tunnel. Disappointing.

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.

Wonderful product to get the right size!

I have purchased multiple different flange sizes from Maymom for my Spectra S1 plus. While I am SO glad they offer smaller sizes than even Spectra offers - these actually dont screw on correctly to the spectra bottles and every Maymom flange Ive tried results in milk leaking everywhere . Its super frustrating and its a significant amount of milk. Unless you use it sitting perfectly still and are super careful when you remove the pump after a session, you will spill milk everywhere. Ive tried the 17mm, 19mm, and 21mm and ultimately while the smaller sizes have helped me out with pump out, the milk leakage is terribly frustrating and disappointing. Ive looked closely and when you twist the flange onto the bottle, it looks like it is slightly crooked. Ive tried all my spectra bottles as my pump came with four. Unless there is another part Im supposed to have to make it twist on correctly, be prepared to leak milk over everything! :/

Exclusive pumper here. Bought the 15mm - yes, actually need them this tiny. Definitely helped with draining the milk significantly faster so that was a win. But dang. The tunnels are SO short, I get sucked all the way down to the end so my nips are hitting the end. Not the answer for super elastic+skinny nips. Ouch!

I’m assuming I’ve just received the wrong item somehow because these are definitely not made for the Spectra and are not the flanges pictured. I’ve included 3 pictures comparing what I received with my current Spectra flanges. As you can see, these are MUCH smaller and the hook up to attach the suction tubing is completely different. My Spectra flange is pictured on the right and this product is on the left (in two of the pictures) and then they are swapped around in the third picture (sorry about that). I’m hoping an easy return will fix this and I’ll receive the correct parts this time. I will update my review.

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

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.

Flange fits me well (please note to buyers: make sure you get sized before purchasing). Works really well with my Spectra S2. Note: where the backflow connects to the flange has a small space but it doesnt have suction loss issues. Flange is easy to clean and fits in my to-go drying rack.

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!
