Flange Inserts 13mm for Medela,Spectra 24mm Shields/Flanges,Compatible with Momcozy S12 Pro/S9 Pro/S9/S12 Wearable Breast Pump,Reduce 24mm Nipple Tunnel Down to 13mm,10PCS

These 17mm flanges have been great! One of my favorite things about them is how versatile they are—I can use them with multiple pumps, including my Momcozy and Medela, which is super convenient. They arrived well packaged and are exactly as described. They’re also easy to clean, which is a huge plus when pumping multiple times a day. The fit works well and they feel comfortable to use. Overall, these are a solid option if you’re looking for compatible, easy-to-maintain flanges. I’m very happy with them and would recommend!

They help me pump using my Spectra

I bought these because my Spectra S1 didn't come with my size (21) and I didn't want to buy all new flanges. These worked wonderfully. They are super inexpensive, fit well into all my flanges (including 22s for handsfree flanges I bought on Amazon before I realized my size), easy to place and stay put during pumping, quality soft rubbery material that reduces friction discomfort from the plastic flanges, and very easy to wash. I would recommend buying these if you want to resize your flanges without dishing out more money for new ones. Hope this helps!

Not bad fit pump well didn’t receive size 18 which I needed

Helped save me when pumping. I recommend ordering the pack that includes the measuring tool also though.

Yeah it’s a good product, I just wish I read the specifications a little better. Because of one of the pictures I thought I was getting 2 of each size since it showed each size x 2 so I was under the impression I would get two of each. Now I need to buy a whole new pack because I need another size 17mm 🤦🏻‍♀️ smh

These made a big difference for me pumping with an electric pump as well as a manual hand pump! I didn’t realize (my own fault) that it only came with ONE of each size. So you’ll need to order two if you want two of the same size.

I bought this twice. First time it had the 2 flanges I needed and they worked fantasticly for me. So decided I'd buy another set so as a gift for my friend who’s pregnant. Just found out that it’s missing one of the flanges which wouldn’t be a problem if she didn’t need that 17mm size. Too late to return it now since I bought and had to wait till the baby shower to gift it. Very disappointing but otherwise good product. As for the product itself they fit perfectly in my 24 size pump flanges and don’t cause any pitching or anything. Only issue is when they get milk behind them they can slide out extremely easily. So don’t turn your flange opening down cuz it may come out and be lost.

Honestly changed my pump game overnight. I was struggling until I inserted a proper flange size. What’s great about this set is you can play around and figure out what works best for you. My advice is to use coconut oil to prevent friction burn. My pump is a spectra s2 and these inserts fit perfectly.

Se adaptaron muy bien a mi extractor

Cumplen su función más no especifica, uo pensé que vendrían dos de cada uno no uno de cada medida, si buscas para los dos aparatos hay que comprar dos paquetes 😅

Parfait pour trouver la dimension qui nous convient sans dépenser une grosse somme.

Pleased with this product. They came as described with one of each flange size and work well with the madela manual pump. If you were using a pump that does both sides at same time may need a different product or two of them, but for the purpose of a hand pump these are great especially at this price point and while figuring out what size I need!
