Maymom Pump Parts Compatible With Spectra S2 Spectra S1, Incl Flanges (28mm) Valves Tubes Bottles Backflow Protectors, Not Original Spectra S2 Accessories Replace Spectra Flange Spectra Duckbill Valve

This product is made by Maymom to fit spectra's S1/S2 pumps in addition to spectra 9 and spectra M pumps. It is known that using the correct size of flange (breastshield) in breastmilk pumping is the most important factor in achieving comfort and efficiency. Every mother was created differently. One or two sizes can't fit all. That is why Maymom develops more than 12 sizes of flanges spanning from 13 mm up to 36 mm to fit the average mothers and those mothers who need special sizes (e.g. 13, 15, 17, 36 mm). For pumping comfort, measure your nipple diameter first (do it after a pumping session), and then use the size selector of this listing to choose the size that is 1-2 mm larger than your nipple diameter, which is measured AFTER a pumping session.

There are improvements of Maymom flange over the original spectra design - 1. In addition to Spectra's duckbills, you can use Maymom duckbills or Maymom valve/membrane system with Maymom flange. 2. In addition to fitting Spectra's backflow protector, you can use Maymom long stem, as well as short stem backflow protectors. You can also use Maymom tubing connector (sold separately e.g. ASIN B0033B9CZ2) to connect Maymom flange to many other popular breastpumps on the market.
