Maymom Pump Parts for Spectra S2/S1 9 Plus — 24mm Flange, Valve, Tubing, Backflow Protector

Overview

Discover a versatile aftermarket option with Maymom pump parts, designed to work with Spectra S2, S1, and 9 Plus breast pumps. This kit provides essential replacements while clearly marked as not original Spectra parts. Included are two 24mm wide-mouth flanges, two valves, two backflow protectors, and two tubes. The flanges are sized for wide-mouth bottles, expanding your bottle compatibility and keeping your pumping routine flexible.

What’s included

• Two 24mm flanges for wide-mouth bottle compatibility
• Two valves for steady, controlled milk flow
• Two backflow protectors to help maintain a closed system
• Two compatible tubing pieces

Interchangeability and practical use

These parts are marketed as aftermarket and interchangeable with Spectra components. They can be used with Spectra flanges, backflow protectors, valves, and tubing. While not original Spectra parts, they offer a cost-conscious way to keep your pump in service, ideal for spare parts, travel, or replacing worn components without purchasing a new unit.

Bottle compatibility and system design

The kit’s flanges are designed to connect with wide-mouth bottles. It works with Spectra bottles, Avent bottles, and Maymom wide-mouth bottles, but it does not support other wide-neck brands. The design emphasizes a closed system with minimal contact between milk and tubing. All parts can be cleaned with water, steam, or boiling water and are BPA-free for everyday use.

Sizing guide and how to choose

• Flange sizes range from 13mm to 32mm in multiple increments
• Refer to the size guide in the product photos to pick the best fit

Safety, testing, and compliance

Maymom emphasizes safety and regulatory context for these aftermarket parts. The kit is BPA-free and test reports are available online. It’s noted as compatible with FDA/EU regulations for materials that contact food, with independent lab tests referenced. As with any pumping component, inspect parts for wear and replace as needed.
