Maymom14mm Flange and Duckbill Valve Compatible with Spectra S1 S2 9 Plus. Not Original Spectra Pump Parts. Replace S2 Pump Parts Flange Duckbill Valve

What can I say? They work just as they should. I did find out they sorta screw onto my evenflo glass bottles so most of the time I just pump straight into those. These are exactly what I was looking for

It works great with my other wide mouth parts for my Spectra S1 and S2. The shield on the flange is wider than the ones I bought from nenesupply which I like. Overall would buy again.

Fits with Spectra S2 pump and bottles, as well as duckbills. Solid construction, works much better than silicone flange adapters on stock supplies. I recommend this over getting adapters.

Perfect dupe for spectra! Definitely recommend

Good quality and doesn't get messed up in sterilizer.

These are great and just like the spectra parts.

These were everything I needed to be successful in pumping. Great timely shipping and overall good product.

Exactly like the spectra brand! Honestly wouldn’t even know the difference. Perfect quality

Las bridas maymom son de material resistente y fácil de utilizar. Siempre y cuando tengas el tamaño de embudo correcto la extracción es indolora.

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.

Ces téterelles s'adaptent parfaitement sur mon Spectra S1.

We received the product couple of months ago. It was up to our expectation. Product was properly packed and reached to us on time. Good buy

Good quality flange, fits spectra perfectly but no valves despite clearly staying flanges + valves. Disappointing as now I'll have to order more.
