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

Good replacement when many backup parts

Perfect replacement parts for Momcozy M9!

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.

Perfect if you have the original M9 parts!

These do not work well at all. With the authentic momcozy parts always being out of stock I had high hopes that this would be a good alternative. I can’t get any milk to come out with these doing a full 30 min session (my normal pump time) when I typically get any where from 7-8 ounces a session. Would not recommend these at all!

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 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

This set of parts fit my M9 well even though it is not the original parts. I like to change my parts every three months to avoid the growth of bacteria and I am glad this one fits well.
