Maymom Pump Parts Compatible with Spectra S2 S1 - Full 13mm Kit

In this review the Maymom Pump Parts 13mm kit is examined for parents who need reliable replacement pieces for Spectra-compatible breast pumps. The bottom line: this kit is best for users who want a complete small-flange backup set that performs like OEM parts while saving money. The reviewer found the kit useful as a ready-made spare parts pack with a clear compatibility promise for Spectra 9+, Spectra S1 and Spectra S2 units, and notes that these are Maymom-made components, not original Spectra accessories.

Key Features

• Compatibility: The kit is compatible with Spectra 9+, Spectra S1 and Spectra S2 pumps so it is easy to swap parts without special adapters.
• Complete small-flange set: Includes a 13mm flange, two backflow protectors, two tubes, two duckbill valves and two wide-neck bottles with travel caps for immediate replacement use.
• Bottle convenience: Bottles include a two-piece travel cap with a rewritable surface so parents can label dates or names and erase easily with soapy water.
• Material safety: Parts comply with FDA food-contact regulations and are BPA-free, so they can be cleaned with boiling water or steam methods.
• Interchangeable design: Maymom parts are made to be interchangeable with Spectra parts, offering OEM-like function for routine pumping and as spare parts.

Who It's For

This kit is for parents who already own a Spectra-style pump and need a compact replacement or spare set, especially those who use a smaller 13mm flange. It is also useful for caregivers who want labelled travel-ready bottles for daycare or outings.

It is not the best choice for people who require original manufacturer parts or those who need dome caps and nipples, since those items are not included. If you need a larger flange size, Maymom offers many other flange sizes beyond 13mm.

Pros & Cons

Cons

• Backflow protectors have mixed durability feedback from customers, so some users may need replacements sooner than expected.
