PumpMom-us Pump Parts for Spectra S1 S2 9 Plus, Compatible with Spectra Duckbill Valve and Silicone Membrane Replace S2 Replacement Parts Accessories

I needed replacement parts for my Spectra pump and I can honestly say it felt better quality. Great value for the money. Easy to install. Would purchase again

Works great after my pump parts turned yellow.

Worried this would not fit the Spectra but they do like new. Excellent price and quality.

These fit my Spectra S1 perfectly and retained shape for several months (I am a part-time pumper)

It's very important to change pumping parts after a couple months of use. I got these to try for my spectra 2 and they fit as expected. They help your pump maintain optimal functioning and good to replace because milk residue builds up after a while even with washing. I like that this is multiple set, affordable, and get the job done!

These are perfect for your spectra pump. You really should be changing these quite often if you pump often/exclusively pump. I do not notice a difference between these and my original pieces that came with my pump. No change in suction or output, great buy and saves $

Since you have to replace parts every month or so this was a great pack

At this point I question whether or not this was sent used. 2 peices had holes in them and 3 of them didn't work as if the texture was to worn out to give suction.
