Valve or duckbill is NOT included in this listing but you can use many valves on the market e.g. spectra valve duckbill or medela valve/membrane. The flanges connect with WIDE MOUTH bottles like Avent bottles, Maymom wide mouth bottle, and spectra wide mouth bottles. IMPORTANT! Not a direct alternative to Spectra 28mm Flange: Maymom 27mm flange features a smoother curvature and a longer, roomier flange tunnel to help reduce nipple pain caused by contact with the back of the flange. Due to design differences, some customers report that our 27mm feels larger than Spectra 28mm. If you're seeking a smaller flange than Spectra 28mm, this product may NOT meet your expectations. Maymom also offers 25mm flange, which is smaller than Spectra 28mm and larger than 24mm. The 25mm flange is recommended for moms with a nipple diameter of 23-24mm after pumping. Please measure your nipple size before purchasing. A detailed explanation is provided in the product images. USED WITH WIDE-MOUTH BOTTLES.
