4PCS Duckbill Valves 2PCS Silicone Diaphragm Compatible with Momcozy M5 Breast Pump, Breast Pump Replacement Parts Accessories for M5,6PCS

Work great on the mom cozy pumps. Saved me some money as these need to be replaced often. The fit and work great.

Ooooh these saved my life. Changing flanges is something I didn’t expect to have to do honestly but it helped get my milk supply back up changing them. This was such a great price for the replacement and made it totally worth it. I highly suggest ordering. These will definitely be a repeat purchase for my next child / pumping journey. If you exclusively pump or pump more than once a day I highly recommend changing often.

Used these as extra parts for my mom cozy as the original parts didn't always dry fast enough for babies next feed was nice to have spare parts waiting.

Perfect replacement at a great price. Used for my M6 Momcozy wearables

Work well in my M5. Much cheaper than through MomCozy.

Got these for my Momcozy M5s and they worked perfect

Works perfectly for not being the brand for spectra!

These are just like the ones from momcozy and I used these for 20 days now and it seemed to have worked great but now my output has not been as good as it used to be and I thought my supply was low but I have another set of parts and I get great output so now I realized it's these parts. They just don't seem to last long for me.
