Duckbill Valve Diaphgram Compatible with Momcozy M9 Replacement Parts, for Upgraded Mobile Flow Parts, Pack of 6

My silly husband ripped the m9 diaphragm by mistake while hand washing and this came in a pinch. It fits perfectly on the Momcozy m9 and I feel this has better suction than the original. The only thing that is different is that this comes in off-white and not the original maroon color but I'm not complaining.5/5

These replacement parts serve their purpose well for those looking to keep their pump functioning smoothly. The components are easy to install and seem to fit well with the compatible system. After using them for a while, they perform reliably, ensuring no interruptions during use. If you're in need of replacements, these parts are a good option to consider for maintaining functionality.

These pump parts fit my device perfectly, and as an exclusive breastfeeder who pumps for a freezer stash, I was pleasantly surprised that my output was an additional ounce more than it typically is after a session. They come in a nice little reusable box that will be handy for keeping the spare parts clean and ready to go. They did have a strong plastic odor right out of the box, so definitely wash them thoroughly and sterilize before use (which one should do regardless!).

These look like they are made very well. I like that the set came with 4 duckbills--I seem to lose those when washing pump parts more than other parts.

These little duckbill valves have been a lifesaver for keeping my pump running smoothly. They snap in perfectly, no weird fit or leaking, and they’re easy to rinse out and dry after use. I go through these often, so having an 8-pack is just plain practical. The quality feels just as good as the originals, if not better. If you’re pumping regularly like I am, this is one of those small things that makes a big difference in the daily grind.

The size and softness are just about what I expected, and it’s pretty convenient to use. The fit is good too. It comes with a small storage case, so I don’t have to worry about losing it after washing. It’s easy to clean and maintain, and I haven’t run into any issues so far. :) Not bad though

These replacement parts are just what I needed for my Momcozy M9! They’re almost identical to the originals and work great. Perfect for having a spare set while cleaning. Will buy again!
