Maymom Two-Piece Wide Neck Pump Parts for Spectra S1/S2 — 16mm Shields & Wide-Mouth Connectors

Overview

Maymom offers a practical upgrade for Spectra S1 and S2 users: a two-piece wide neck pump parts kit. This set combines a 16mm shield with two wide-mouth connectors to form a complete flange assembly designed for comfortable daily use and double pumping sessions. The design emphasizes ease of use, straightforward cleaning, and flexible compatibility with common hands-free pumping bras.

What’s inside and how it works

• Contents: two shields (16mm) and two wide-mouth connectors. The 16mm shield is intended for mothers whose nippie diameter is roughly 14–15mm after pumping. Together, the shield and connector create a functional flange for double pumping.
• Two-piece flange design: separable flange components that are easy to assemble, disassemble, and clean. This construction is designed to fit most hands-free pumping bras and home-made bras. Available shield sizes include 10mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 22mm, 23mm, 24mm, 25mm, 27mm, 28mm, 30mm, 32mm, 34mm, and 36mm.
• Compatibility details: compatible with Spectra Pump S1, Spectra S2, and Spectra 9 Plus. Designed for widemouth bottles (Spectra wide-neck or Maymom widemouth bottles). For Medela bottle compatibility, Maymom also offers a bottle converter option.

Safety, materials, and quality

All parts that contact breast milk are BPA/DEHP free. Maymom reports production in a US FDA-inspected facility, with test reports available via online access. Packaging is retail poly-bagged and sealed by the manufacturer; this set is not an original Spectra flange or accessory.

Care, fit, and real-world use

The two-piece design supports flexible assembly and alignment, which may help you tailor the fit to your body and workflow. The flange assemblies are intended to be disassembled for thorough cleaning between sessions, then reassembled for the next pumping. This kit is compatible with most hands-free pumping bras on the market and works well with both Spectra and Maymom widemouth bottles.

Usage tips and practical notes

• To maximize compatibility, choose the shield size that best fits your post-pumping diameter, then pair with the wide-mouth connector for a complete flange.
• Disassemble after pumping, rinse, and sanitize using standard baby-safe methods to keep parts in good condition for repeated use.

While this set is designed to work with Spectra S1/S2 pumps and compatible bottles, it is not original Spectra hardware. If you need to use a different bottle brand, consider the Maymom bottle converter for additional compatibility options.
