Maymom Pump Parts Incl Duckbill Valve with Pull Tab Silicone Diaphragm Compatible with Spectra S1, S2, Synergy Gold; Not Original Spectra Pump Parts; 10 pc Blue

These insert into the bottom as opposed to going over them like the others I have bought. This makes them so much more user friendly and easier to remove! I hope they last a while, time will tell.

Fit perfectly on my Spectra S1 breast pump. I love the duck bill valve because it has the tab that you can pull to get it out without damaging or stretching the valve itself.

Amazing! I got the pink spectra in January and every sense opening it the white duckbill valves have fallen off mid pump every single time and was so irritating these ones that go on the inside work amazing and have never fallen off!!!

My favorite plastic replacement parts for spectra!

If you have any aftermarket spectra lids with flange built in, double check the type of duckbill it will take. The duckbills did not work as they are a male (duckbill) to female (lid) and my aftermarket can only take female. Bummer as I didn’t notice until too late but ordered ones that will work.

These are really nice. I might have a pumper for 13 months now. And they really kept up their suction, but I do rotate them out.

did not like these for replacement parts, felt too flimsy

Great replacement parts!

je ne vois aucune différence avec les anciens model c'est juste du marketing ...
