PumpMom 21mm Pump Parts for Spectra S1/S2/9 Plus – Flange Set, Valves, Backflow Protectors, Tubes (Not Original)

A complete, comfort-forward replacement kit for Spectra pumping

The PumpMom 21mm Pump Parts kit is designed to complement your Spectra S1, S2, and 9 Plus pumps with a focus on fit, feel, and reliable airflow. This 7-piece set is offered as a non-original option that aims to align with your daily pumping routine without compromising on safety or usability. Each component is built to work together so you can quickly swap in replacements when needed, keeping your sessions smooth and consistent.

What’s inside the 7-piece set

• Two 21mm flange/shields for a comfortable, natural seal.
• Two duckbill valves to support steady airflow while maintaining gentle suction.
• Two backflow protectors to reduce contamination risk along the tubing path.
• Two tubes to renew your setup and keep pumping continuity intact.

Comfort and fit you can feel

The PumpMom flex shield features a soft rim designed to sit softly against the skin, aiming for a natural feel during long sessions. The shields use an oval shape and a broad 106° opening to help distribute pressure more evenly, which may contribute to a comfortable, secure seal as you pump.

Potential performance improvements

Results can vary by user, but you may notice a steadier seal and more uniform suction with the wide-angle design and improved shield geometry. The kit emphasizes consistent airflow and durable construction, supporting repeated use in daily pumping routines.

Safety, materials, and compatibility

• Made from food-grade polypropylene (PP).
• BPA- and DEHP-free for peace of mind.
• Sealed by the manufacturer for traceability and quality control.
• Fully compatible with Spectra S1, S2, and 9 Plus breast pumps.

Important notes

These are PumpMom parts, not the original Spectra components. Always inspect parts for wear and replace as needed to maintain pumping performance. Clean and dry parts after use to help preserve seal integrity and airflow.

Real-life use ideas and care

Use these parts at home or on the go to refresh a tired setup, or as a backup kit when originals aren’t available. For care, rinse with warm water after pumping, air-dry fully, and store in a clean, dry place out of direct sunlight.
