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

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’ll take it since there aren’t a ton of options when you don’t fit the standard flanges that come with every pump, but they do leak if you’re not careful. A rubber gasket would go a long way to seal the top. If I lean too far forward because my toddler needs something, I can feel milk dripping off the side of the collection bottles.

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.

Just like the Spectra flanges. If youre pumping and not getting anything out but still left with full breasts, your flange is probably too big. If youre using the standard 24mm honestly its probably too big. You have to measure the nipple only, just the little button, then add a few mm to it. I was having an awful time pumping, kept feeling numb, starting getting less and less milk but constantly felt my letdown forcefully. I measured my nipple finally and after trying the 19mm first, seemed to find a perfect fit here. Your areola should not be going into the flange! Thanks maymom!

Just what I needed. Works great with my spectra s2 breast pump

They work with the motif Luna for anyone else wondering!

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 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! :/

Hated spending so much for the 17 mm as I had already recently bought the 20mm, but it is SO WORTH IT. I have short, flat nipples and with the standard 24 mm flanges, my poor nips always felt terribly bruised. I would get tears in my eyes if my children or husband accidentally bumped my chest. According to the ‘measure after pumping’ rule and using a mm sizing guide, the 20mm should fit but I must have nips that swell to fit all available space. With these, my areola isn’t being painfully sucked into the flange. No more bruised painful feeling! I exclusively pump and use these for 4 30 minute pumping sessions every day. They have held up very well, no signs of wear and are easy to clean. If you’re on the fence, buy them! I actually might be able to go a size smaller but I’m happy with these. Thanks Maymom!
