Perfect replacements
These replacement parts have worked perfectly with my Momcozy M6 pump and made it feel like new again. The duckbill valves fit securely and create a good seal without leaking, which is something I had issues with when my original ones started wearing out. The silicone material feels soft yet sturdy, and it snaps easily into place on the pump without needing any adjustments. The diaphragms also fit tightly and maintain strong suction throughout a full session. I can tell the quality is high because the suction stays consistent and there is no loss of efficiency even after multiple uses. I like that the set includes twelve valves and diaphragms since it gives me plenty of spares to swap out regularly for hygiene and performance.After several weeks of daily use, these replacements have held up very well with no stretching or tearing. I clean them with warm soapy water after each session and they still look and function like new. The silicone has not discolored or absorbed odors, which shows it is a good grade of material. The suction strength feels just as good as the original Momcozy parts, and I have noticed my pumping sessions are faster because I am not fighting with reduced flow. Having this many pieces in one pack is convenient since I can rotate them and always have a fresh set ready. Overall, these replacements are a dependable and affordable option that keep my M6 pump running smoothly and efficiently.

they fit my breast pump
After my baby was born, I had been using a breast pump for a while now. The Momcozy m6 pump work good for me, but the diaphragm and valves I have to replacement them every month. I am glad that I found this replacement parts and I after a few research I ordered them with no hesitation. I appreciate the clear instructions on how to replace and install it, which make the installation so easy. So far, they have been working good. No leaking milk while pumping, and they are easy to clean. After using them, I boil the water to 100 degree Celsius first, then I put them in to wash it. They are supposed to last about one to three months, and that is the recommendation from the instruction. I don’t see any difference from this replacement parts compare to the original one; in fact, I think this one works better, and seems like the milk comes out a little bit faster.

Great Extra Valves/Diaphragms for My Momcozy – No Leaks, Easy to Clean!
I wanted an extra set of parts for my Momcozy M6 breast pump and found this kit and am quite impressed. I got the six piece kit which includes 4 duckbill valves and 2 silicone diaphragms. The parts fit my pump as well as the originals, and the silicone feels soft and flexible. I also was pleased to find that there is no ‘plastic’ scent as I have had issues with other no-name brands. I have had no problem with the valves sealing or leaking. Cleanup is as easy as the OEM parts. By having the extra parts I can always ensure I have a clean set on-hand without non-stop washing. The installation was as easy as the originals. I really liked the included plastic carry case as well and will likely repurpose it after I stop pumping. All in all this set met my needs and am really glad to have the extra parts for my pump!

Easy to clean
I recently got this 6-piece duckbill valve and silicone diaphragm kit for my pump, and I’m impressed with how well it fits and works. The pieces are soft and flexible, and the silicone doesn’t have any weird smell. Everything fits onto my pump, with no leaks or loose seals, so I can use it without worrying about performance. The included plastic carry case is nice —it keeps everything organized and clean when I’m not using it. I like that these replacements are made from food-grade silicone, and they look just like the original parts. Cleaning is easy; they rinse off quickly and dry without any residue. Having a few extras helps streamline my daily routine since I don’t have to wash the same set every time. They’re easy to install, maintain, and come ready to use right out of the box.

Safe and affordable to use
This set of 6PCS M6 duckbill valves and silicone diaphragms are really practical! I bought it to use it with my Momcozy M6 mobile breast pum. Although it is not the original part, it is very compatible, the size is accurate, and it is completely tight, does not leak air, and the suction is stable and powerful! Silicone is very soft and elastic, completely odorless, and it is safe to use! It is also very convenient to clean, easy to disassemble, fast to clean, and can be used again after drying! A set of 6 pieces, the price is much cheaper than the original factory, and the quality is equally excellent, which is very cost-effective!
