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 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!

These fit my Spectra S1 perfectly.

If youve been told your a size 17 then buy these! Having appropriate flange size pumping parts is vital to pulling the most milk possible. Most pumps come with larger flange size parts, so I desperately needed these. They worked well. The suction was strong and efficient without being uncomfortable. These worked lovely with my Spectra S2 pump. Dont hesitate- but them!

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!

I cant believe the smaller size flanges are so hard to come by. I would not recommend smaller than a 17, no matter the size of your nipples, because its impossible to center in a smaller flange. Ideally, I would probably use their very smallest size, but even a 15 was almost impossible to center a nipple in. This is just physics and nothing against them. I wash my flanges by hand, and they have always held up for the duration of my pumping journey.

Compatible with spectra pump! Going down a bit from the factory size is alot more comfortable!

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 was nervous to buy these because the smallest flange sizes Spectra had on their website was 20mm and I was worried these wouldn’t fit with the system. These flanges fit perfectly with all the parts that come with the Spectra pump and having the CORRECT size flange made my life bareable again! I was about to give up on breastfeeding and pumping until I finally saw a lactation consultant at 6 weeks out and found out the 24mm flange that comes with the spectra pump was way too big and causing me extreme radiating nipple pain. The consultant recommended I try the 17mm. I looked all around and I HIGHLY recommend these for anyone experiencing nipple pain from pumping with the wrong size flanges!

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

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!
