Maymom Wide Neck Pump Part for Spectra S1/S2 – 21mm Wide Mouth Flanges Replacement

Premium compatibility and flexible design

Discover a Maymom solution designed to complement your Spectra pumping workflow. The Wide Neck Pump Part includes two 21mm wide-mouth flanges that are compatible with Spectra S1, S2, and the Spectra 9 pump. This set can serve as an easy-to-install replacement option for the Spectra Shield (21 mm two flanges). It’s crafted by Maymom, not the original Spectra manufacturer, and carries no official Spectra affiliation. The BPA-free construction aligns with FDA expectations for plastics that touch foods, offering a reassuring material profile for everyday use.

In addition to the flanges, the kit is designed to work with a range of bottle options, including Spectra wide mouth bottles, AVENT bottles, and Maymom wide mouth bottles. Note that these parts are not compatible with other wide-mouth bottles outside this family, so compatibility is important when planning to mix and match gear.

What’s included

• Two 21mm widemouth flanges designed for Spectra S1, S2, and Spectra 9 pumping systems
• Compatibility as a replacement for Spectra Shield (21 mm two flanges)
• Maymom-made, not an original Spectra part; Maymom is independent of Spectra’s trademark owner
• BPA-free, with materials that comply with US FDA regulations for contact with foods
• Dishwasher-safe (top rack) and steam sterilization capable
• Works with Spectra wide mouth bottles, AVENT bottles, and Maymom wide mouth bottles

Practical use, care, and setup

• Care and cleaning: top-rack dishwasher safe and steam sterilization friendly help keep equipment ready for repeated use
• Flexibility in setup: choose a flange size that fits different nipple diameters measured after pumping, offering a more customized experience
• Compatibility note: designed specifically for Spectra-style systems and compatible bottle formats; not suitable for other wide-mouth bottle brands
• Brand clarity: this is a Maymom accessory, with clear distinctions from the original Spectra components

Real-life pumping sessions can feel calmer when you can tailor the flange setup to your needs. The two-flange bundle gives you a practical option for quick swaps or backups while you focus on comfort and routine. While benefits like fit and ease of cleaning are supported by design, individual results may vary. Always inspect parts for wear, and follow recommended cleaning and sterilization steps to maintain performance over time.
