Maymom 21mm Flange and Duckbill Valve Compatible with Spectra S1, S2 and 9 Plus

Flimsy with rough edges.

Good

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!

Recomendo esta marca, porque realmente é compatível. O material é semelhante ao da Spectra, não noto diferença. Apenas uma nota para quem encomenda o ⌀21mm, encomende um número menor porque eles não tem o ⌀21mm e enviam o ⌀22mm, como podem ver na embalagem.

Perfect for my spectra s1 arrived fast and price was awesome

I bought a full kit before, but it was really hard to fit and not very comfortable, so I decided to try this flange instead. Honestly, the quality is even better than the original one. The edges are smooth, the size fits perfectly, and most importantly, it’s comfortable to use. I don’t feel any pain at all. Plus, it’s HSA eligible, which is a nice bonus. really happy :)
