Maymom 20 mm Flange Insert Pink – Elvie/Medela Shield Compatibility

Overview

The Maymom 20 mm Flange Insert Pink is a soft, silicone accessory designed to customize shield fit for a more comfortable pumping experience. Supplied as two 20 mm inserts, it nests inside compatible 24 mm shields to create a snug, fuller opening without changing your routine.

This is an aftermarket insert and not an original Elvie replacement part. It’s crafted from BPA free silicone and is intended to support a smoother pumping posture when used with various shield setups.

What it is and how it works

The insert reduces the 24 mm shield nipple tunnel to a 20 mm opening, enabling a closer, potentially more comfortable fit. The design aims to work with a wide range of shield configurations while keeping your current handsfree bra intact.
