Maymom Pump Parts for Spectra S1 S2 9 Plus – 14mm Flange, Valve, Tubing, Backflow Protectors

Overview

Maymom offers aftermarket pump parts designed for compatibility with Spectra S1, S2, and 9 Plus electric breast pumps. This kit is not original Spectra parts, but it provides a curated set of components that many caregivers find convenient for ongoing pumping needs. The package emphasizes interchangeability and practical use, helping you maintain your pumping routine without being tied to a single original part line.

What’s Included

• 2 x 14mm flanges
• 2 x valves
• 2 x backflow protectors
• 2 x tubings

The flanges are designed to connect to wide-mouth bottles, expanding bottle compatibility beyond Spectra’s own options. This kit is sold in a retail pack and is suitable for cleaning using common methods such as water steam or boiling water.

Interchangeability and Bottle Compatibility

• All parts are interchangeable with Spectra pump parts, including flanges, backflow protectors, valves, and tubing.
• Works with Spectra bottles, Avent bottles, and Maymom wide mouth bottles. Not compatible with other wide-neck bottles.
• Designed as a closed system with no contact between milk and tubing when assembled correctly.

Sizes, Safety, and Maintenance

• Available in multiple flange sizes (13–32mm); refer to the size guide in product photos to select the right fit.
• Parts are BPA-free and have undergone independent lab testing; test reports are available for reference.
• Regular cleaning is recommended; all parts are suitable for steam or boiling-water sanitation as part of routine care.

Usage Considerations

While these Maymom parts are designed for broad compatibility and ease of use, they are aftermarket accessories. They offer flexibility for users who want to mix bottle options or maintain a back-up set of components, without making guarantees about performance beyond stated compatibility.
