Maymom 2x 21mm Wide-Neck Pump Flanges for Spectra S1/S2 – BPA Free

Overview

Maymom offers a practical, BPA-free replacement option: two 21 mm wide-neck flanges designed to work with Spectra S1/S2 Plus pumps and the 9 pump variant. This set serves as a convenient alternative when you need a fresh component that fits a range of bottle sizes and compatible pumps, all while maintaining a comfortable pumping experience. Note that these are Maymom-branded parts and are not original Spectra components.

Why it matters

These flanges are sized for a nipple diameter around 18-20 mm measured after pumping, which can help you reconfigure your setup without purchasing a new pump. The kit can also be used with Ameda Mya, Mya Pro, and Motif Luna pumps, broadening the potential use across a few popular brands.

• Compatibility: Spectra S1/S2 Plus and the 9 pump, plus select Ameda and Motif pumps.
• Materials and safety: BPA-free, FDA-regulated plastics suitable for contact with foods under applicable rules.
• Bottle compatibility: Works with Spectra wide mouth bottles, AVENT bottles, and Maymom wide mouth bottles.
• Care: Top-rack dishwasher safe; steam sterilization compatible.
• Important caveat: Not compatible with other wide-mouth bottles beyond those listed; not original Spectra parts.

In everyday use, these flanges can be a practical addition to your pumping toolkit. They’re light and compact, making it easy to switch between bottles and pumps on busy mornings. If you’re stocking up on parts, this pair offers a cost-effective option to keep your equipment ready for quick cleaning or replacement after regular wear and tear.

Care and usage tips

• Rinse and air-dry after use to maintain the seal and fit.
• Follow top-rack dishwasher guidelines and steam sterilization when needed.
• Check nipple diameter after pumping to confirm the best fit for comfortable expression.
