NENESUPPLYDuckbill Valves Compatible with Spectra Pump Parts Compatible with Spectra S2 S1 9 Plus Breast Pump Replace Spectra Valves and Spectra S2 Accessories

I'm thankful for this brand. These are on point for quality and function. Just like the real things. And it's so nice to be able to afford backups of pump parts to have on hand when pump efficiency drops!

These have worked great with my Spectra S2. One broke when removing it, but it may have been how I grasped to remove it.

These fit perfect on my Spectra Pump - can’t beat the price!

Works perfect for my spectra 2.

Some of the Q & As made it seem like these would be compatible with the Ameda Breast pumps (I have the Mya Joy PLUS), and they are not. I really like this type, so I'm sad that they're not compatible!I didn't put 5 stars, because I wasn't able to use them, so I can't give them that high of a score, but the quality and type was exactly what I was looking for, so I'm assuming they're at least a 4+. I just wanted to make sure other people could find a review that says they're not compatible :)

Es tremendo producto para remplazar las valvulas de fabricación que traen las maquinas extractoras.Me ayudó a mejorar mi tiempo en extracción de leche materna.

Works perfectly! I have a spectra and these are just as good if not better than the ones at Spectra sales, and this way you get a lot more for less money- I have used them a couple of times so far and they are still in good shape, the fit is good and you can push it on there to where it’s tighter but you don’t have to (and really aren’t suppose to) for it to work

I bought these as a replacement for my Spectra duck bills. I was tired of spending so much money every month on name brand so I decided to give these a try. I was very surprised with these. I have not noticed any loss of suction or milk production while using these. They are also a lot easier to get of then other brands. I always make sure I have a pack of these on hand now.
