## Description

desertcart.com : 2PCS Duckbill Valves & 2PCS Diaphragm Compatible with Momcozy M5 Wearable Breast Pump, Replacement Pump Parts Accessories Compatible for M5 Momcozy, Not Original Mom Cozy Accessories : Baby

Review: Fits Perfectly - Be Careful with Washing - Having extra collector cups is such a lifesaver while pumping and these are perfectly interchangeable with the momcozy ones. Be careful how you clean them though, I microwave steam them when I'm in a pinch, and I learned that after a while, it messes up the flanges.
Review: Better output! - Works very well with mom cozy pump and goes together tighter. Finding I’m getting more output from these cups than I was with original set. Also cheaper to buy individual than any “set”. Helps with EP and having a backup to not wash immediately

### ⭐⭐⭐⭐⭐ Fits Perfectly - Be Careful with Washing
*by C***A on March 12, 2026*

Having extra collector cups is such a lifesaver while pumping and these are perfectly interchangeable with the momcozy ones. Be careful how you clean them though, I microwave steam them when I'm in a pinch, and I learned that after a while, it messes up the flanges.

### ⭐⭐⭐⭐⭐ Better output!

### ⭐⭐⭐⭐⭐ It’s a little hard to take off, but works!!!
*by Y***E on February 20, 2026*

I was so worried about ordering these and hoped they would fit my Momcozy pump. Luckily they snap right on and work just as good as the original parts. However, they are difficult to take off of motor. I don’t know how to explain it. I almost took off a star but since it still works well and saved me money, I decided not to. It’s just a little frustrating when it’s time to remove them from the motor. But I would definitely still recommend them instead of paying nearly triple buying the actual replacement from Momcozy.
