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

Fit perfectly in my Spectra! I love that the parts come in a little case to keep for the next change out. I pump eight or more times a day and haven't seen a decrease in my output at all. The pulltab makes it so much easier to remove the duckbill valve, and it's PINK! Overall would recommend these replacement parts!

Was gifted a set before and purchased them again as replacements. Unfortunately I didnt get to use them because my journey ended unexpectedly.

Works perfectly for the motif Luna

The diaphragms are nice and more sturdy than the original parts that came with my motif luna. however the duckbills are too long to fit into the spectra/motif flanges. i even tried to trim them down and there wasn't a seal, I'm so disappointed because I wanted to have duckbills with the pull tab on them. Not only are they too long, but the openings are super open (see image) I'd rather use the original so that I know it has a good suction and won't impact my already low supply.

I got tired of my other duckbills falling off these do not fall off at all. So glad I bought these!

These are great. The color is easy to see in the water when washing. They fit perfectly in motif and spectra flanges. They don’t fall out mid pump like some have.

These were as good as my spectra parts and the pull thing helps remove the duckbill super easily

I don’t get the suction I was getting on the other duckbills. I just don’t think they hold up as well on my spectra S2
