Silicone Diaphragm Compatible with Momcozy/TSRETE/HAUTURE/PADRAM/LoveOfLive/OMFMF, Use with Wearable S9 Pro/S10/S12 Parts Replace, Wearable Breast Pump Accessories (4 Piece Set)

They fit will with my Momcozy S12 Pump. the duck valves are a little longer then the factory ones but they work i just have to make sure they are all the way on when assembling the pump.

Does not fit momcozy s9 pro. They are two long

A perfect fit to replace on the s12 breast pumps. Cheap and easy to replace. Durability is great. Easy to clean and wash. Dries fast for easy next time use. I would recommend or buy again!

I'm always a little nervous to order a part that is compatable with another brand, but these duck bills fit my MomCozy pump PERFECTLY at such and affordable price!

Muy buenas las valvulas, el material se ve y se siente de calidad.

Bought this for my Tsrete since it says it is compatible. The duck bill is to big and does not fit snuggly therefore not usable. Went with a different brand.

They fit and work nicely, after a while I change them cause they get loose and also stained.

I loved the size and durability of these. Other brands tore when cleaning (especially the small attachment on the end) but these haven’t ANY issues (3 months now). They fit my Mom Cozy S9 perfect & I prefer them over what came with the pumps originally.
