Spectra Duckbill Valve for S1, S2 Breast Pumps (Pack of 2)

The Spectra Duckbill Valve Set is designed to increase suction and provide better output during breast pumping sessions while preventing backflow contamination. Each duckbill valve consists of one piece, making it easier to clean and maintain. 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.

A Spectra duckbill valve is compatible with Spectra S1 Plus, Spectra S2 Plus, Spectra 9 Plus, and Dew 350 pumps.

Spectra recommends replacing your pump parts every 3-6 months for optimal use.
