5Pack Silicone Duckbill Valve & 4Pack Silicone Diaphragm Compatible with momcozy S9 / S12 / S9Pro / S12Pro Wearable Breastpump, Breast Pump Replacement Parts, Breastfeeding Essential Accessories

I originally ordered these to use on my momcozy S12 but I ended up using them with my hand pump (evenflo brand) and my wall pump. They are pretty universal and they actually worked better and stayed out better on my momcozy! The duckbill that originally came with my momcozy kept sliding off while I was pumping no matter what I did (I only used it 3 or 4 times before this) I popped one of these on and it works a lot better and stays put. Also easier to cle.

These work great. I used them with the Legendairy Milk Cups.

These are compatable with the Medela hand pump. I struggled because I feel like my milk never really came in and with the addition of the duckbill flange helped me get every drop out. I was able to provide my baby atleast with some breastmilk for the first month and a half of her life thanks to these.

I read the reviews before ordering and so happy with the product! I ordered these for my momcozy S12 and they work perfect! I will keep ordering these.

It does its job but not as soft as the originals so takes another few seconds to put together the pump parts.

Worked great as replacement parts for my pump and I saw no difference between these and the brand named ones. Save your money and get these instead!!
