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 previously ordered silicone flange inserts to size down existing flanges, but I had a hard time using them because I couldn’t see my nipple through them well enough to tell if it was centered or not. Since purchasing these, I don’t want to use the others even though they’re the same diameter. I replaced my duckbills at the same time as switching to these flanges, so I can’t say that it’s all due to these, but my milk output is SO much higher, and I can empty my breasts in much less time than I was previously. Highly recommend these.

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 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.

I’ve went back and forth between Maymom and Nene supply and discovered I prefer Maymom more. One thing is the consistent breast shield size. I purchased the 17mm but have large boobs (before even BFing) and was pleasantly surprised that the shields were bigger than the 19mm from Nene. Way more comfy!

I’m really happy to have a properly sized flange & good quality duckbill valves. While the lid screws onto & “fits” the Spectra bottles, it is NOT as good a fit as the Spectra flange lids. It seems like the tops may have too much tread, so if you bend over & your bottle happens to tip, it will leak around the tread. If you advertise something as fitting, that should not happen. I cannot tell you how upset I was when I noticed the amount of milk that spilled around the tread of a closed bottle. No bueno. I think I will just get flange inserts and use the Spectra flanges to prevent any spilling. Annoying.

I had to leave a review because maybe it could help some mums out there. I was using the spectras 20mm and 21mm, I was experiencing sensitivity & pain. I had read about the importance of flange size so I decided to purchase these in 18mm (for references my nipple size pre pumping is 15mm and post pumping 17mm). Well long story short, wow, the difference is just wow. Don’t give up and find your flange size, it will drastically change your pumping for the better. No more pain, yay.

Unfortunately I was not able to use this. It’s my second set I have bought. I use my other set with my travel pump. I love these products but before using it cracked. I was hand washing it and noticed it was cracked on the tunnel. Super sad since these aren’t exactly cheap....

Just as good as the ones that come with your pump but way better! It’s so nice to have one that fits properly, it has definitely helped with comfort and getting milk out! And yes it does fit on the spectra pump’s!

These fit perfectly with my Spectra 2 pump. Just what I needed!
