Maymom Pump Parts for Spectra S1/S2 – 6-Piece Duckbill Valves & Silicone Membranes (White)

Meet the Maymom 6-Piece Replacement Set for Spectra S1/S2

Keep your breast pump performing at its best with the Maymom 6-piece replacement set. This pack includes four duckbill valves and two silicone membranes crafted for reliable, everyday use. The parts arrive in a clean white finish and come in retail packaging for safe storage and convenient refresh when you notice a change in performance.

What’s included

• 4x duckbill valves
• 2x silicone membranes

Compatibility and brand scope

These parts are not original Spectra components. They’re designed to work with Spectra S1/S2 setups while also offering broad cross-brand compatibility. The duckbill valves fit both Spectra and Maymom flanges, and silicone membranes work with Maymom backflow protectors (Long, Short, and Medium) as well as Spectra S1 and S2 backflow protectors. The set is also compatible with Motif Luna and with Ameda Mya and Mya Pro lines, giving you flexible options across your collection. Note: not for Ameda Mya Joy.

Performance and maintenance

To help maintain pump performance, replace the silicone membranes and duckbill valves regularly. Fresh parts can help restore a responsive feel and maintain suction power comparable to OEM valves. The parts are BPA and DEHP free, designed to meet regulatory standards for materials that contact food, and are packaged in a sealed retail pack for safety and cleanliness.

Quality, safety, and testing

• Part materials comply with EU and USA FDA regulations for items that contact food
• Independent lab testing with available test reports for reference
• All items are sealed by Maymom in retail packaging
• Parts can be cleaned with boiling water or steam

Color options and packaging

In addition to white, Maymom offers the parts in pink, blue, and orange to match different pump aesthetics and personal preference. The retail packaging keeps contents secure and organized, whether you’re stocking up or replacing parts on the go.
