Maymom MyFit Flange Set Compatible with Spectra S2 Spectra S1，19mm Shield Widemouth Connector 3rd Gen Duckbill Valve ，Not OEM Spectra Pump Parts Spectra Flange Spectra Valve

Fits my Spectra S2 perfectly and does not leak. I like that it comes with a set of duckbill valves as well. Its always nice to have an extra set so when one loses its suction I don't have to rush out to the store to grab a new one. It is nice that it can come apart to slide into my pumping bra since some pumping bras don't allow you to slide the entire flange in. Very versatile in that aspect. Overall it is as it was described by the seller. Nice quality for a nice price. Especially since it is hard to find a comfortable flange for 19mm. Works great! No complaints here!

Great pump parts at a great price! Fit my spectra perfectly.

I have this flange and the single piece. This two piece one has a smaller cone shape making it less comfortable. It is also a longer tunnel so it makes the bottle sit out much further. Technically it works fine but it is not nearly as comfortable due to the shape.

I have elastic nipples, I alternate between these and pumpin pals flanges. These are amazing. I highly recommend!

Works great. Thought the 2 piece would be easier to use/maneuver with a pumping bra than the traditional 1 piece that fits spectra. Didnt seem to really make much of a difference. Still a great alternative to the name brand flanges.
