Maymom Two-Piece Wide Neck Pump Parts for Spectra S1/S2 Pumps – 14mm Shields, BPA-Free

Overview

Maymom offers a versatile two-piece wide-neck flange set designed for Spectra pumps (S1, S2, and compatible models). This replacement kit emphasizes fit, easy cleaning, and flexible use with wide-mouth bottles. It is not the original Spectra flange, but it is built to pair with Spectra S1/S2 systems and Maymom wide-mouth bottles for a range of pumping setups.

What’s Included

• 2 shields (14mm)
• 2 wide-mouth connectors

The 14mm shield is indicated for mothers with a nipple diameter of roughly 12–13mm after pumping, helping tailor the fit without sacrificing performance. The two-piece flange design supports straightforward assembly, disassembly, and cleaning, which can be helpful for daily routines.

Design, Fit, and Use

The flange is a separable two-piece construction, which some users find easier to clean and adjust compared with one-piece designs. It also fits most hands-free pumping bras on the market, as well as various home-made bra setups. In addition to the included 14mm shields, Maymom lists a broad shield size range to accommodate different comfort preferences.

• Available shield sizes include 10mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 22mm, 23mm, 24mm, 25mm, 27mm, 28mm, 30mm, 32mm, 34mm, 36mm.
• The set is designed for double pumping and works with Spectra wide-mouth bottles; Maymom also offers a bottle converter for broader compatibility.

Compatibility and Practical Use

Designed for Spectra Pump S1 and S2 and the Spectra 9 Plus, this kit is compatible with widemouth bottles. If you’re trying to use Medela bottles, Maymom recommends their Third-Gen Bottle Converter for an alternative pairing. This expands the potential configurations for existing pumping gear while keeping milk-contact parts BPA/DEHP free.

Safety, Quality, and Packaging

All components that touch breast milk are BPA/DEHP free. The parts are produced by a US FDA-inspected company, and test reports are available via Maymom’s online resources. The kit is retail poly-bag packed and sealed by the manufacturer. This is an aftermarket option and is not labeled as original Spectra S1/S2 accessories.

Why Consider Maymom

For caregivers seeking flexible flange options, Maymom’s two-piece design offers practical advantages in terms of assembly, cleaning, and compatibility with various bottle types and pumping bra setups. While results can vary by individual, the set presents a range of sizes and a two-piece construction that may fit some users more comfortably during longer pumping sessions or double-pumping routines.
