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

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

I would definitely recommend because they are good quality and fit perfectly with mom cozy .

These fit perfectly on my momcozy pump. I had no clue they had to be replaced and it made such a difference. So great for the price.

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

I lost the nipple portion of my Momcozy breast pumps and these fit like a glove! Glad I ordered these as a replacement!

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.

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.

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