Contains 6pc Ultra Clear Duckbill Valves with a reuseable storage box. It is clear to see through so you can clean it better.Work with Spectra breastshields and Maymom breastshields for spectra pumps. Designed for these breastpumps: Spectra S1, S2, Spectra 9 Plus, Spectra Dew 350 breastpumps. See photo illustrations for compatible breastpumps.
One duckbill valve can replace a spectra valve and a spectra membrane. No need to buy extra membranes. Mothers have fewer pump parts to wash, sterilize, and assemble.
Built with high stretching material so it will last longer (see photo of this listing). Ultra thin lip areas to provide faster and better flow of milk, and reduce the milk backing up to the tubing. Compatibility guaranteed!
Made from BPA free Materials, and can be sterilized in water steam or boiling water. Comply with EU and US FDA regulations for materials that contact food. Every batch is tested by independent labs for quality and safety.
