5Pack Silicone Duckbill Valve & 4Pack Silicone Diaphragm Compatible with momcozy S9 / S12 / S9Pro / S12Pro Wearable Breastpump, Breast Pump Replacement Parts, Breastfeeding Essential Accessories

These fit my MomCozy s12 great and lasted a couple months of wear

Compatible with maymom wearables

Good for replacement, works as the original ones

These fit perfect on my mom cozy s12! The duckbills last quite awhile before having to be changed.

First of all if you are a stickler for packaging this isn’t for you.. box is taped shut with scotch tape sooo. However, the product itself seems pretty great quality at affordable price point. This was purchased for my mom cosy and the peaces worked well with it. I’ll be keeping and would recommend.

I purchased the momcozy wearable s12 pro pump with my own money, so I was not receiving replacement parts from insurance. These replacement parts are enough to make it feel like a new system! They fit well and wash easily, and are a great value to improve the functionality and lifespan of my wearable pumps.

Very nice quality. Had to return because I read somewhere they are compatible with the Baby Buddha expression cups. The duckbill valves are but the silicone diaphragms are not. I was impressed with how thick the silicone is and the pieces are packaged very nicely

They fit my mom cozy s12 pumps perfectly!
