Overview

Maymom offers a complete set of replacement pump parts designed to refresh Spectra-compatible breast pumps with practical reliability and straightforward maintenance. This kit targets Spectra S1, S2, S3, and 9 Plus models, delivering a full mix of components to renew worn pieces without needing the original Spectra parts. The focus is on real‑world usability, combining durable materials, flexible compatibility, and simple cleaning for everyday pumping.

What’s in the package

• 2x backflow protector assemblies (each with 2 large caps, 2 small caps, and 2 silicone diaphragms)
• 4x duckbill valves
• 2x silicone membranes
• 2x tubing

Compatibility and fit

• Compatible with Spectra S1, S2, S3, and 9 Plus breast pumps. The duckbill valves are also compatible with Spectra Dew 350.
• Not original Spectra parts; refer to the photos for exact compatibility notes. Maymom parts can work with Maymom and Spectra flanges, and the tubing is suitable for Ameda Mya pumps.

Performance and safety

Designed to deliver suction performance on par with OEM parts, these components are BPA/DEHP-free and come in retail packaging. The closed system helps prevent milk from entering the tubing, which many caregivers find reassuring during busy days. Independent safety testing is available for reference in the product line.

Care and cleaning

All parts are designed for straightforward cleaning. The closed-system design minimizes contamination risk, and components can be cleaned with water, steam, or boiling water between uses. This flexibility makes maintenance easier when juggling feeding schedules.

Quality and packaging

Maymom provides independent lab testing reports and adheres to EU and USA FDA guidelines for materials in contact with food. The retail packaging is sealed by Maymom, offering a neat, ready-to-use kit for storage or travel.

Real-life use cases

In everyday routines, caregivers appreciate having a ready replacement kit to swap worn parts quickly, reducing downtime during early morning feeds or hectic workdays. The backflow protectors help keep the tubing clean, the duckbill valves maintain a responsive seal, and the membranes accommodate different flange styles. With travel or multiple pumps in a household, this set adds flexibility and peace of mind.

Tips for best results

• Inspect parts for wear and replace worn duckbill valves or membranes to maintain performance.
• Match the backflow protector style to your Spectra model; refer to the photos for compatibility.
• Sanitize parts by water, steam, or boiling water before first use or after heavy use.
