Maymom Pump Parts for Spectra S1/S2 (9 Plus) – Duckbill Valve & Silicone Membrane Replacement

Overview

Maymom offers replacement pump parts designed for Spectra S1 Plus, Spectra S2 Plus, and Spectra 9 Plus models. This set contains x duckbill valves and x silicone membranes. These are not original Spectra parts, but they are a practical option for routine maintenance and ongoing compatibility with your pumping setup. The color options (white, pink, blue, orange) can help you quickly identify the right parts and coordinate with your device aesthetic.

Regularly updating worn components may help preserve the pump’s feel and efficiency, potentially supporting steadier performance across sessions. Maymom’s parts are packaged in retail-ready packaging and are designed to be easy to replace, with a focus on straightforward care between uses.

Compatibility and Fit

The duckbill valves are designed to be compatible with Spectra flange and Maymom flange, maintaining a comparable suction profile to the OEM valves. The silicone membranes work with Maymom backflow protectors (Long, Short, and Medium) as well as Spectra backflow protectors, making them a flexible option for mixed-brand setups. The set is also noted as suitable for Ameda Mya pumps, broadening its use beyond a single system.

• Same suction power as OEM valves, helping to preserve pumping effectiveness
• Backflow protector compatibility across multiple brands
• Versatile use with Spectra S1, S2, and related components
