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).
