Editorial Review After market pumps parts made by Maymom to be used with breastpumps with closed systems like Spectra S1, S2, 9, Medela Freestyle, Medela Swing-maxi, Ameda Purely Yours, Avent Comfort. This is just one part of the whole spectra s1 and s2 accessories. You will also need other parts e.g. flanges (Medela/Maymom only; this part is not compatible with original flange of S1/S2 pumps), tubing etc to make the pump function.
Features 1) Long Stem Maymom Backflow Protector to fit between Medela Breastshield (flange) or Medela PersonalFit connector or Maymom flange and Spectra S1, Spectra S2 spectra 9 pumps 2) Replaces Spectra backflow protector and Maymom's spectra yellow adapter 3) Allows spectra pumps to remain a closed system 4) NOTE: This backflow protector can't connect to Spectra original flanges that use a backflow protector. Please buy from ASIN B01BREQFME for this purpose 5) This part functions as "Maymom's yellow adapter for spectra pumps"+"Original Spectra Backflow Protector".
