Momstouch 29mm Flange for Spectra S1/S2 – Wide-Mouth Replacement (Not Original)

Flexible, Compatible 29mm Wide-Mouth Flange by Momstouch

This Momstouch 29mm wide-mouth flange is designed as a practical replacement option for popular breast pumps, including Spectra S1/S2 9 Plus, Motiff Luna, and Ameda Mya. It offers a comfortable, broad opening that supports a steady pumping rhythm for many moms. Because it isn’t the original Spectra part, it’s best viewed as a compatible alternative that expands your setup while you search for exact parts or a temporary fix during busy weeks.

Though not an original Spectra component, this flange is engineered to work with a range of Spectra accessories—such as the valve, backflow protector, and Spectra bottles—alongside other wide-mouth bottles from brands like Avent and Momstouch. The goal is a flexible, budget-friendly option that can fit into your existing workflow without requiring a full equipment swap.

Compatible Partners and Bottle Versatility

• Two 29mm wide-mouth flanges per package, suitable for Spectra S1/S2 9 Plus and select models like Motiff Luna and Ameda Mya.
• Works with Spectra wide-mouth bottles, Avent bottles, and Momstouch wide-mouth bottles; compatible with most other wide-mouth designs.

Material, Safety, and Sanitation

• Composed of BPA-free materials to support daily pumping routines with peace of mind.
• Sanitization-ready: safe for steam cleaning, boiling water, or microwave-steam bag sanitation, helping you keep gear clean between uses.

Practical Fit and Care Tips

Before you buy, measure your nipple diameter to ensure a good fit—these flanges are described as suitable for nipple diameters roughly in the 25–27 mm range. If your setup includes compatible Spectra parts or wide-mouth bottles, this flange can slot into your existing kit as a replacement or supplementary option.

For daily use, consider this product if you value flexibility, cost-conscious replacement options, and a wide-bottle ecosystem that can accommodate different brands. As with any accessory, verify fit with your specific pump model and bottle collection to maximize compatibility and comfort. This flange is presented as a compatible alternative aimed at widening your pumping possibilities, not a guaranteed replacement for every device.
