Best replacement parts for my Spectra S2
These replacement parts for my Spectra S2 were exactly what I needed! The set comes with clear instructions and images, which made swapping everything out super simple, even for someone like me who usually finds pump parts confusing. I especially appreciated the QR codes included; they linked directly to step-by-step instructions and even to individual replacement parts if I ever need to reorder just one piece.The parts themselves feel durable and well-made, and they fit my S2 perfectly without any issues. Everything works smoothly and has held up well after multiple uses and washes.It’s such a relief to have a compatible, high-quality option that makes pumping easier and less stressful. Highly recommend for any Spectra S2 user who wants reliable replacement parts without the guesswork!

Great for spectra pump
These work great with the spectra s1 pump. They are easy to clean and have lasted 6 months of pumping so far, just make sure to replace the duck bill valves. Very impressed with the quality!

Perfect fit!
Get the spectra! And get the right flange fit with these!! After finally finding my perfect size flange, I was so upset that Spectra didn’t have a set in my size. I was also worried that these wouldn’t work as well as they branded ones, but these are perfect! I recommend getting a back up set, too!

They work!
Fit my Spectra and my breast/nipple very well. I was hesitant to buy more than one set at a time, but I recommend getting a few so it’s one less thing to worry about later (pumping is hard!)

Game Changer for Pumping with My Spectra
I use a Spectra pump, and switching to the Maymom 21mm flange and duckbill set has made a huge difference. One of the most important things I learned is that flange sizing really matters — figuring out the correct size for your nipple is essential for both comfort and milk output.The 21mm fits me so much better than the standard sizes that come with the pump. The suction is strong and consistent, and the duckbills work perfectly without leaking. They’re also easy to clean and hold up well with daily use.Having the right size flange truly changed my pumping experience, and I’m so glad these affordable replacements are available. A must-have for any Spectra mom!

What size did i buy?
The are compatible with my spectra and I like having the extra duck bills. My biggest gripe is that the size of the flange is nowhere on the flange. I had bought multiple sizes to see which fit better and couldn’t tell them apart

Great project my supply went up right away after I started using those flanges
Amazon Customer –
Good quality flange, fits spectra perfectly but no valves despite clearly staying flanges + valves. Disappointing as now I’ll have to order more.

Was good but not sure how to test different size
Terrible! The glue did not work and the nails were poor quality. The colour does match to picture –
Product works great. Using it on a Spectra S2 machine
