I got the momcozy S12 pro through Aeroflow and as soon as I got it I realized I’d need a different size flange than what came with it. The Aeroflow website only allowed you to order individual sizes and I wasn’t 100% sure what size I’d need and I know they can change throughout the breastfeeding journey so I wanted to try and find a multi pack. Amazon to the rescue! These fit and work perfectly with the Momcozy s12 pro and it’s all of the sizes you could possibly need.

This was super helpful for my pumping journey. Having the right size flange helps a lot when you are a low supplier. I like this kit because it gave me multiple options to try to figure out what size was best for me. I found these fit on both my hands free pump and my stationary pump.

I used these flanges with my Spectra S2 pump! They work perfectly and have made pumping so much more comfortable for me. I’m a size 17mm which is pretty small and not easy to find, so I’m grateful for the wide variety of sizes offered for such a cheap price. They are also easy to clean.

I didn’t know I was going to need different sizes when I got my wearable and hospital grade pumps but these are great! I also didn’t know that the sizes change throughout the bf/pumping journey so it’s helpful that it gives you multiple sizes! I have 3 different brand of pumps and they work for all of them.

Worked great for the price and comes with a lot of options for sizing.

So glad I got this. Increased my milk production a few ounces on my portable pumps. Definitely have recommended to others!

The universal flanges that come with the pumps don’t work for everyone. These flanges help tremendously.
