Spectra Duckbill Valve for S1, S2 Breast Pumps

The Spectra Duckbill Valve is designed to increase suction and provide better output during breast pumping sessions while preventing backflow contamination. Each duckbill valve is one-piece, making it easier to clean and lasts longer. Spectra Duckbill Valves are made of silicone and quality tested to ensure a sturdy grip on small, medium, large, or x-large breast shields and flanges. All Spectra Breast Pump parts that come in contact with Breast Milk are BPA-free.

For use with Spectra S1, S2 &  Dual S Breast Pumps.
