Momstouch 23mm Flange for Spectra S1/S2 9 Plus – Replacement Pump Parts (Synergy Gold)

Momstouch 23mm Flange: a flexible replacement for Spectra and wide-mouth bottle systems

This 23mm wide-mouth flange from Momstouch is designed as a practical, user-friendly alternative to OEM parts. It fits a range of Spectra models, including the S1 and S2, as well as 9 Plus and Synergy Gold. While it is not an original Spectra part, it is engineered to work with Spectra components such as valves and backflow protectors, and it supports a variety of wide-mouth bottles. The flange is sized for nipple diameters in the 19–21 mm range, offering a snug, comfortable seal while you pump, and it’s built for straightforward cleaning and sanitization between uses.

Two key benefits at a glance

• Wide compatibility with Spectra S1/S2, 9 Plus, Synergy Gold, and notable third-party bottles.
• Includes two 23mm wide-mouth flanges for flexible setup and easy replacement.
• Not original Spectra; a reliable replacement that can integrate with Spectra valves and backflow protectors.

Fit, use, and everyday practicality

Whether you’re refining comfort during longer pumping sessions or juggling multiple bottle brands, this flange supports a steady, secure seal. The wide-mouth design facilitates smooth attachment to Spectra wide-mouth bottles and is compatible with Avent and Momstouch wide-mouth bottles as well, making bottle switching less cumbersome. Targeted at nipple diameters in the 19–21 mm range, it offers a practical, adaptable option when an exact OEM fit isn’t available.

Materials, care, and safety considerations

• BPA-free construction for everyday use with peace of mind.
• Sanitization is straightforward: steam, boiling water, or microwave-steam bags are suitable options.
• Designed to work with Spectra components like valves and backflow protectors to help maintain a clean setup.

Real-world use scenarios

In daily routines, the Momstouch flange can simplify bottle transitions during pumping, especially while traveling or pumping at work. A secure seal and compatible design can reduce fiddling and make quick bottle swaps easier. The option to mix and match with Spectra, Avent, and Momstouch wide-mouth bottles gives you practical flexibility as your pumping setup evolves.
