Maymom 3rd Gen Thread Changer – Spectra S1/S2 Wide Mouth Flange Converter, No Leak

Overview

Meet the Maymom 3rd Gen Thread Changer, a genuine Maymom bottle size changer designed to simplify your pumping setup. It features a precision-built anti-leak o-ring and a textured, anti-slip surface for a secure grip. The result is a smoother screw-on experience that works with both wide-mouth flanges and standard bottles, helping you streamline bottle interchange without fuss.
