Maymom 16mm Wide Neck Pump Part for Spectra S1/S2 – Compatible with Motif Luna

Product overview

The Maymom 16mm Wide Neck Pump Part offers a flexible interface for pumping setups, acting as a third‑party flange designed to bridge several popular systems. It is intended for Spectra S1/S2 wide‑neck configurations and also supports Motif Luna and Ameda Mya pumps. This is not the original Spectra flange, so actual fit can vary by model and individual anatomy. If you measure a nipple diameter around 14 to 15 mm after a pumping session, this flange may provide a comfortable alternative worth trying.

Key compatibility and sizing

• Includes two 16 mm wide mouth flanges designed for Spectra S1, Spectra S2, Spectra 9 Plus, Motif Luna, and Ameda Mya family pumps.
• Suitable for nipple diameters about 14–15 mm measured after a pumping session.

Bottle interface and versatility

• Works with Spectra wide‑mouth bottles, Avent bottles, and Maymom wide‑mouth bottles.
• Not compatible with every wide‑mouth bottle brand—double‑check your setup before use.

Safety, materials, and care

• Made by Maymom and BPA‑free; adheres to FDA guidelines for plastics that contact food.
• Not affiliated with Spectra or its trademark owner; intended as a compatible third‑party part.

Care and cleaning are straightforward. The part is designed for easy maintenance and can be placed on the top rack of a dishwasher. It is also steam safe, supporting quick sterilization between uses. When assembling, ensure a secure seal with your chosen bottle and pump model to help minimize leaks during pumping.

Practical use scenarios include home pumping with a flexible bottle lineup, traveling with different bottle brands, or testing a different flange size for potential comfort and interface improvements. While these outcomes are possible, results will vary based on fit, pump model, and individual pumping routines.
