Maymom Breast Pump Parts - Compatible With Spectra S1/S2, 28mm Flanges & Accessories Kit

Breastfeeding moms, meet your new favorite pump parts! This complete Maymom replacement kit works perfectly with Spectra S1 and S2 breast pumps, giving you everything you need for comfortable expressing. The kit includes two 28mm flanges (available in multiple sizes from 15mm to 32mm), duckbill valves, backflow protectors, tubes, bottles with travel caps, and wide-mouth base connectors. These aren't original Spectra parts, but they're designed to work exactly the same way with identical suction power. The bottles feature a clever rewritable surface on the caps - perfect for labeling with dates or your baby's name using a regular pen or dry erase marker (just wipe clean with soapy water). All materials are BPA-free and meet FDA regulations for food contact safety. You can sanitize them using steam, boiling water, or microwave steam bags with complete confidence. Whether you're replacing worn-out parts, need extras for convenience, or want different flange sizes for better comfort, this kit has you covered. The quality construction ensures durability through many uses, making your breastfeeding journey smoother and more comfortable. Keep a spare set on hand so you're never without your pump when you need it most!
