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)

Love how these fit well with my Spectra pump parts!

So thankful for these!Pros:- Fit the Spectra S2 pump parts- Smaller than the ones that come with the pump so they fit me better- Produced more milk with less pain due to the better fitCons:- Don't have any!

I bought these to go along with my Spectra and they fit perfectly. I do with the pink valves were easier to get off, but other than that I have no complaints. I used the Earth Mama nipple cream and it cleans off easily. It's hard to find flange sizes that small since average is 24! But this fit true to size. If you are part of the kitty bitty titty committee, you may have some extra room with them being wide mouth flanges but this never affected the actual flange size around your nipple.

I bought these after a recommendation from my lactation consultant, and I’m so glad I did! They fit perfectly and are so much better than the ones that come with the machine. My only wish is that the original product included all size options, as not everyone has the same needs. Overall, these have made a noticeable difference in my pumping experience!

Affordable flange, fits spectra S2

I have always thought I had a problem producing with my first two children, but I still am giving it a go with my 3rd that I birthed last week. I could never really pump more than 3 oz in a whole day between both boobs combined. Turns out I was just using the wrong flange size! I used the standard 24mm that came with my Spectra’s and then did some research on how to increase my supply and lo and behold, I needed the tiniest flanges that exist after learning to measure myself. These 13mm flanges have made so much difference in just a single day! I went from pumping 3 oz combined in a whole day to almost 4 oz just from the right and 2oz just from my slacker lefty in only 3 pumping sessions!!! To say I’m impressed is an understatement. I haven’t tried to wash them in the dishwasher yet to see about quality but I’m currently in love with how much these have helped me not feel like as much of a failure as I have been. Purchased 3 sets lol

Unfortunately the standard flanges for the Spectra were way too big. My lactation consultant recommended the 17 mm size and these are a great fit.

I'm thankful to have proper sized flanges for my nipples, but I really wish they would change the shape of the cup so my breasts fit better inside. I'm constantly leaking milk out the side of the cup as I pump no matter how I place them! It's quite irritating and confusing.
