Calling all pumping moms! If you're using a Spectra S2, S1, or 9 Plus breast pump, these PumpMom oval flanges are about to become your new best friend. The 17mm size with that innovative soft rim makes pumping so much more comfortable - no more soreness or discomfort during those long sessions. The oval shape is genius because it actually fits better during pumping, which means better suction and more efficient milk expression. They're made from BPA-free, food-grade materials so you know you're getting the safest option for you and your baby. Each set comes with 2 flanges and 2 duckbill valves - everything you need for a complete upgrade. The 105-degree wide angle opening is specifically designed to create that perfect fit that standard round flanges just can't match. Whether you're exclusively pumping or supplementing, comfort matters, and these deliver. So many moms tell us they wish they'd found these sooner - the difference in comfort is seriously night and day. Plus, they're compatible with all the popular Spectra models, so you can upgrade your pumping experience without buying a whole new pump. Your pumping journey just got way more comfortable!
