Silicone Membrane Diaphragm Designed for Spectra S1 S2 9 Plus Breastpump Backflow Protector Also for Maymom Backflow Protector Long Medium Short Stem, Not Original Spectra Accessories Pump Part

Great quality works perfectly.

Great quality, works perfectly witb Spectra 2. Color is nice

When the membrane diaphragms that came with my Spectra S1 pump just weren’t adequately doing the job anymore, I found these! After reading through the reviews, I decided these would best fit my needs. I like that they feel a little thicker than the Spectra ones, so I’m hoping they may last longer. I also like that they have different colors! I went with the pink to match my duckbills from Legendairy. I’m very pleased with these and will order again in the future!

I didn't realize at the beginning of my pumping/nursing journey just how many pump parts have to be replaced regularly. I bought bunches of these diaphragms to keep my pump running well and maintain my excellent output. Worked very well for me.

Perfect for my Spectra S1 pump!! Good quality and affordable. Glad to be stocked up on replacement parts.

Works super well! Love the pink color.

Worked fine with my spectra pump, was able to Mix and match them with my existing pieces, easy to wash and clean. No issues, would recommend.

Love these, such a great replacement option! Can’t tell the difference and the colors help me figure out which ones are new when I boil all together.
