Spectra | Valve Membrane Set

The Spectra Valve & Membrane Set is used to create suction to draw out Breast Milk while pumping. The membrane opens and releases during pump cycles, allowing proper connection to the breast. This can be used as a replacement for the Spectra Duckbill Valve in the Spectra S1 Plus, Spectra S2 Plus, Spectra 9 Plus, and M1 breast pumps. This valve and membrane set provides the same functionality as the duckbill valve but with an alternative two-piece design. Two valves and two membranes are included in each set and can be used as spare parts whether you’re on-the-go or need to keep an extra supply at home or work. Spectra Valves & Membrane Sets are specifically designed and authenticated for Spectra Baby USA Breast Pumps
