Maymom Flange Inserts 17 mm for Medela, Spectra 24 mm Shields/Flanges, Momcozy/Willow Wearable Cup. Compatible with Medela Freestyle, Harmony to Reduce 24mm Nipple Tunnel Down to 17 mm; 2pc/Each

These work perfectly with my Elvie double pump. The pump came with multiple flange sizes, all too big for me. This works with any of them to adapt them to my size- painless pumping sessions with great output.

I use the Elvie Stride with 24mm cups, and these 18mm inserts fit perfectly. They slide in easily and stay in place without moving.Since switching to these, pumping has become so much more comfortable — no more pain or irritation, and I even get more milk out. The material is soft but sturdy, and they’re easy to clean by hand.Definitely recommend for moms who need a smaller flange size!

Needed these to put inside my 24mm flanges and they fit like a glove, so easy to use. It closed the suction and was much more comfortable with my nipples. I used them inside both my momcozy pumps as well as my motif pump. The silicone is very high quality and easy to clean with a little soap and water. Best bang for your buck, highly recommend!

The media could not be loaded. I have two sets of these and they are amazing. They fit in my Elvie stride and my spectra S2 pump. These are a game changer and help me so much with out put and comfort.

I have an Ameda Mya pump and from my beginning my flanges were too big. The pump only came with 24-mm flanges and at the start of breastfeeding this time (this is my second child, I had pumped for 14 months with my older daughter) I ordered the 21-mm flanges. Those worked for months of pumping 3-4 times a day, but when my daughter turned 9 months, I noticed my pumping output suddenly decreased to a point that I was not pumping the equivalent of what my daughter drinks at daycare in a day. I first thought that the valves needed to be replaced and that didn't help. Then I tried to boost my supply by eating oatmeal, but no such luck. After some research, I realized that my flanges were much too big. Unfortunately, Ameda does not make anything smaller than the 21-mm flanges. I found this insert on Amazon and decided to give it shot. Immediately my output improved. I am back to pumping enough (and then some). These inserts fit into the 24-mm flanges that came with the Ameda Mya pump. I have to really shove them in there and it's a tight squeeze, but they fit. My old con for this product (and reason for 4 stars) is the inserts are opaque and it is hard to see the alignment of the nipple within the flange. I kinda have to feel it out to make sure nothing is rubbing on the sides, because it is not easy to see. Otherwise, I am overjoyed that I found this product and I can keep up with pumping for the time being.

I had looked around for silicone flange inserts for pumping when baby 2 arrived this past summer; these did not disappoint!I didn’t have silicone flange inserts with our first and that really hindered my motivations for pumping because of how uncomfortable it was for me. I was determined this second time around to be successful pumping. These Maymom inserts made pumping comfortable for me! Easy to clean and soft silicone material. I did also use a pumping lubricant with these silicone flange inserts. Fit in both my portable pump flanges and my stationary pump flanges. Best piece of advice; make sure you measure your nipple size correctly! That along with these soft inserts can go a long way for a mama’s pumping journey.

A just have when your flanges aren’t the right size. Helped my milk flow and production. They fit just right. Would highly recommend

I like these inserts but they do not work for allflanges. These were way too big for my 24mm spectra flanges. However, they work well for my Elvie stride and Medela flanges. Also note that they are pretty thick, so I have to use higher suction to get decent output. Not my favorite 17mm flanges.
