Maymom Pump Parts for Spectra S2/S1/9 Plus – 19mm Flange, Valve, Backflow Protector & Tubing

Maymom Pump Parts for Spectra S2, S1, and 9 Plus

This Maymom aftermarket pump-parts set is designed to work with Spectra S2, S1, and 9 Plus breast pumps. The kit includes two 19mm flanges, two valves, two backflow protectors, and two tubings. They are not original Spectra parts, but Maymom components are engineered to be interchangeable with Spectra pieces. The kit is intended for use with wide-mouth bottles only and uses a closed-system design to minimize milk contact with tubing.

This compatibility-focused option offers flexibility for replacements or upgrades. You can pair Maymom parts with Spectra flange, backflow protector, valve, and tubing to extend the life of your equipment and simplify replacements. Note: these parts connect specifically to wide-mouth bottles, including Spectra, Avent, and Maymom wide-mouth bottles. They do not fit other wide-neck bottle types.
