Maymom 25mm Flange for Spectra S2/S1 9 Plus – Replacement Pump Parts by Maymom

Discover the Maymom 25mm flange kit designed for Spectra S2, S1, and 9 Plus pumps. This replacement set emphasizes compatibility and practical convenience, offering a cost‑conscious option without sacrificing interchangeability with the Spectra family. Each component is crafted to fit snugly and perform consistently in everyday use.

What’s included and how it helps

• Two replacement tubes designed for reliable airflow and solid connections with Spectra parts.

• Two bottles with a two-piece travel cap; the cap surface is rewritable for labeling dates or baby names when you are on the go.

Key benefits and practical uses

• Maymom-made components are designed to perform well alongside OEM parts, providing a cohesive pump-part ecosystem.
• Available in multiple flange sizes (including 15mm to 32mm) to help you find a fit that feels right for you.
• The two-piece label-cap on the bottle supports easy daycare labeling and daily organization—erase with soapy water.
