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. Used as a replacement for the Spectra® Duckbill Valves, the Spectra® Valve and Membrane Set provides the same functionality but with an alternative two-piece design. Two valves and two membranes are included in each set. Can be used as spare parts whether your on-the-go or needing to maintain an extra supply at home or work. Spectra® Valve & Membrane Sets are specifically designed and authentic for Spectra® Baby USA Breast Pumps.
