8pcs Duckbill Valves and 4pcs Silicone Diaphragms Compatible with Momcozy Mobile Flow M9, Mom Cozy M9 Replacement Accessories, Breastfeeding Parts, Replace for Momomzy Valve Diaphragms

Even better than the original ones! Work perfectly fine.

Was waiting for Momcozy to have restock of replacement parts for my mobile flow m9, and after a month of checking amazon, came across these replacement parts. They work perfect for my pump.

The diaphragms work great. Some of the duckbills worked better than others, but overall they’re pretty decent. This set seems to be decent quality overall and a more cost effective replacement set for the M9. I’d buy it again.

Took me a while to find the right fit for my pumps these were them! For the momcozy hands free

Extremely poor quality. None of the duckbills sealed.

The diaphragms were a perfect dupe! The duck bills; however, make me want more from them. They fit fine, but the slit across the duck bill were a bit off centered? I’m fairly sure that’s my issue with the product. It feels like they’re getting worn down a bit more quickly, so I was replacing them again in just a week- mind you, I use my M9 pumps 3x daily when I work. So if we do the math- I had to replace them after using them 21 times, whereas I didn’t need to replace my original Momcozy duck bills for a full month and a half.If you’re gonna get these, get them for the diaphragms, not for the duck bills

justo lo que necesitaba

Fit the momcozy M9 pumps perfectly and are actually more durable and less likely to tear than the OEM version.
