Maymom 19mm Wide Mouth Flange & 2nd Gen Pink Valve for Spectra S1/S2, Luna Pumps

Overview

The Maymom 19mm Wide Mouth Flange set provides a flexible, compatible addition to your pumping toolkit. This two‑flange package includes a 2nd Gen pink valve and is designed to work with select Spectra S1/S2 Plus pumps, Motif Luna, and Ameda Mya pumps. It is not the original Spectra flange, and Maymom operates independently of Spectra.

What’s Included and Fit

• Two 19mm wide-mouth flanges
• One 2nd Gen pink valve
• Compatible with Spectra S1/S2 Plus pumps, Motif Luna, and Ameda Mya pumps

The 19mm opening aligns with a nipple diameter range of roughly 17–18 mm after a pumping session, per the product notes. If your measurements fall in this range, the fit may feel comfortable during sessions. As with any replacement part, comfort and performance vary by individual anatomy and pump setup.

Bottle and Accessory Compatibility

• Works with Spectra wide-mouth bottles, AVEN bottles, and Maymom wide-mouth bottles
• Not compatible with other wide-mouth bottle brands

Think of this as an alternative option to expand your bottle-pump pairing. Review your current setup to ensure a secure seal and proper alignment during pumping.

Care, Safety, and Maintenance

• BPA-free; complies with US FDA regulations for plastics that contact food
• Top-rack dishwasher safe; steam-cleanable for convenient cleaning between sessions

Usage Tips and Real-Life Scenarios

For best results, verify the fit with your body and pumping habits. After pumping, inspect edges and the valve for wear. The components are lightweight and straightforward to swap in your chosen pump system, offering flexibility if you use multiple bottle options or want a different flange size on different days.

Brand Transparency

Maymom offers this part as a compatible option rather than an original Spectra component. It is not affiliated with Spectra’s trademark owners. Always confirm compatibility with your specific pump model and bottle system to ensure reliable operation.
