This product is made by Maymom to fit spectra pumps. It is known that using the correct size of flange (breastshield) in breastpumping is the most important factor in achieving comfort and efficiency. Every mother was created differently. One or two sizes can’t fit all. This 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). Measure your nipple diameter first, and then use the size selector of this listing to choose the size that is 1-2 mm larger than your nipple diameter AFTER a pumping session.

  •  Compatible with all Spectra pumps (S1/S2/M/9+) and older Spectra breastpumps (Dew 350, 360)
  •  Connects directly to Spectra backflow protector; no need for yellow flange adaptor!

 There are improvements of this flange over the original spectra design

  1. In addition to spectra’s duckbills, you can use Maymom’s valve/membrane system with this Maymom flange. You can also try other brands of duckbills/valve/membrane on this flange. The chances are that they will fit.
  2. In additional to fitting Spectra’s backflow protector, you can use Maymom’s long stem, as well as short stem backflow protectors. You can also use Maymom’s tubing connector (sold separately) to connect this flange to many other popular breastpumps on the market.

    Kulily offers the most complete range of sizes for the breast shield. It works for my spectra S1 plus breast pump. The product is made in Taiwan.
    Overall the service is prompt and good. Product is good. However the membranes is different from the original one. In my opinion the original spectra membrane works better
