Maymom 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

Bought these to use with my Spectra S1 and they worked perfectly! Finding affordable and fun (pink!!) replacement parts for your pump is always a win in my book!

Works great with my spectra!

These replacement duckbill valves are great. They were delivered quickly and are a very cost-effective option compared to the brand name parts.They function just the same as far as I can tell in terms of output, so I have not noticed any difference at all when using them.I also really like that they come in different colors. It makes it easy to keep track of which parts have been replaced and which ones still need to be, which is super helpful when rotating pieces. Overall, a great value and I would definitely purchase again.

These work perfectly in my Spectra parts set up for my Baby Buddha pump.

Great quality works perfectly.

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!

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

These work great! I have the spectra s1, I bought these as a replacement and they have exceeded my expectations. First, they don’t attract lint and and pet hair like the original ones and they also work well as a backflow membrane. I had a stream that was spraying out a little high and when I finished pumping there was almost 1/3 of the space full of milk. However when I removed the milk and took the membrane off, the space behind it that leads to the spectra was bone dry.
