Maymom 19mm Flange Set for Spectra S1/S2/9 Plus – Replacement Pump Parts (Not OEM)

Upgrade your Spectra pump with Maymom replacement parts

Designed to work with Spectra S1 Plus, S2 Plus, and 9 Plus pumps, this Maymom set combines essential components you rely on during daily pumping. The bundle includes two 19mm flanges, two bottles, two duckbill valves, two backflow protectors, and two tubing sets—ready for use when you need a trusted replacement kit.

Note that these are Maymom-made compatible parts, not the original Spectra components. They’re designed to fit Spectra flanges, valves, backflow protectors, and tubing. If you own a Spectra Synergy Gold, a tubing adapter may be required. If you’ve misplaced your tubing adapter, consider Maymom’s Tubing Adapter (ASIN: B09XF18WZ7).

Engineering and design for reliable performance

• Valve tips are precisely engineered to minimize gaps and suction loss; easy to install and remove. Interchangeable with Spectra S1 and S2 pump accessories.
• Wide-neck flanges feature a smooth angle and extended tunnel for a comfortable pumping experience and a versatile size range.

Comfort, stability, and fit

The flanges come in sizes that cover a broad fit spectrum (13mm–32mm), helping you tailor the setup to your preference. Bottles stay securely in Spectra holders, with a locking tab to help prevent detachment during pumping. The included bottle holds up to 160mL and sits on a stable, anti-tip base. All materials are food-safe and FDA-compliant, with independent testing reports available upon request.

Bottles, stability, and safety in daily use

Pairs of bottles are designed to stay put in the connector, reducing tipping during movement. The 160mL capacity supports routine sessions without frequent refills. The combination of secure bottle placement and a robust base helps keep pumping sessions calm and manageable, whether at home or on the go.

Practical use and considerations

This Maymom parts set is crafted to complement Spectra pumps for everyday pumping, spare-part backups, or travel kits. It’s designed to fit Spectra S1/S2 holders for a secure connection. If you own a Spectra Synergy Gold, be sure to check whether a tubing adapter is needed.
