Duckbill Valve and Silicone Diaphragm for Wearable Breast Pump, Compatible with Momcozy S12 Pro/S9 Pro/TSRETE S12,etc S12 Wearable Breast Pump Parts Accessories Replace (4 Piece Set)

These work great for both of my hands free pumps. Fits well and good quality.

Perfect fit on my momcozy S9 was worried that it wouldn’t fit but it’s tight & snuggle has a better suction (better than the original pieces) now that I replaced these after 6 months of not changing them. Would definitely recommend & are cheaper than at the momcozy website. Would purchase again when needed to replace it’s recommended every 3 months or so.

They stay in my breast pump very nicely and are super easy to clean defiantly recommend

LONG LASTING

fit my momcozy dupe pump perfectly, increased output a lot!

The media could not be loaded. Mi extractor es un S12 y estuve leyendo los detalles para hacerme una idea si eran similares o noPero este ni si quiera le queda es muy grande me decepcionó porque tenía la esperanza que sirvieraSi tienes el mismo problema y el mismo tipo de extractor no gastes tu dinero en esto porque no sirve ni le queda

The duckbill valve rubs against the pump reservoir, preventing the pump from actually working. My pump was one of the pumps advertised for these valves. The silicone diaphragm fits perfectly, but the duckbills are useless.
