Maymom Flange Inserts 13mm for 24mm Shields – Medela/Spectra/Momcozy & Willow (2pc)

Overview

Maymom Flange Inserts 13mm tailor the fit of 24mm shields and wearable pumping cups across a broad range of brands. Each package contains two 13 mm silicone inserts that slip inside 24 mm shields, narrowing the nipple tunnel for a more personalized feel without requiring a full shield change. The inserts are BPA-free, food-grade silicone and designed with everyday use in mind, balancing comfort with compatibility.

Compatibility & Range

These inserts are designed for broad compatibility with many popular 24 mm shield configurations, including Medela PersonalFit Flex 24mm, Motif Luna 24mm, Elvie 24mm variants, Momcozy S9/S10/S12, Willow wearable cups, LegendaryMilk 24mm, Tsrete wearables, and Ameda Mya 24mm flanges. Sliding a 13 mm insert inside a 24 mm shield offers a narrower tunnel option while preserving your current hands-free bra setup.

What’s in the Box

• 2 x 13 mm inserts
• Short version with snug fit for this size

Real-Life Scenarios

Whether you’re winding down with a late pumping session or commuting with a hands-free bra, the 13 mm option can pair with your 24 mm shields to offer a distinct tunnel feel. It supports ongoing experimentation with fit while keeping your existing equipment in play.

Fit, Use & Maintenance

The 13 mm insert delivers a snug feel inside the shield and does not require trimming. To install, place the insert inside the 24 mm shield before attaching to your pump or hands-free bra, then rinse with mild soap and water after use. Allow to air-dry before storing.

• Compliant with US FDA regulations for food contact

Size Options & Versatility

In addition to 13 mm, Maymom offers a range of sizes (21, 19, 17, 15 mm) to support varied shield diameters. This breadth helps you explore different tunnel feels while staying with your preferred shields.

Tips for Testing Comfort
