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

Fit just like original pieces!

Gotocut brand duckbill diaphragm is generically designed for Momcozy M9 breast pumps. If you are looking for inexpensive replacement parts, this is a solid choice. Easy as original parts to use and clean. Comes in a sanitary storage case which is good for travel.

These Momcozy M9 compatible replacement parts are a worthwhile, affordable option for maintaining your pump's parts that wear out in time. The pack includes a useful number of duckbill valves. However, be aware of the strong plastic odor, requiring thorough washing and sterilization. While I appreciate the included storage container, I find it unnecessary and prefer a lower cost without it. The parts fit well and are easy to use, making them a practical choice despite the initial smell.

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.

So glad I found these affordable replacements for my worn-out valves. They fit the M9 perfectly and restored my pump's suction power immediately. The material feels durable, and I appreciate having extras on hand. But functionality-wise, they perform identically to the pricey official replacements.

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 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!).
