MilkFlow 21mm Breast Flanges 2-Pack for Medela & Lansinoh Pumps

Overview

Introducing the MilkFlow 21mm Breast Flanges 2-Pack, thoughtfully designed to work with a range of popular breast pump models. These compatible parts are built to fit Medela pumps such as Pump in Style with MaxFlow, Symphony, Freestyle, Sonata, Swing, and many Lansinoh pumps. This listing represents compatible accessories, not original components, offering a reliable option to expand your pump kit with a consistent size in a two-pack for convenience.

With comfort in mind, MilkFlow renders a practical blend of width, contour, and flexibility to help you find a position that feels more natural during pumping sessions. The design emphasizes a broader cover and an oval, rotatable shape that can adapt to different body shapes and pumping rhythms.

Below you’ll find a deeper look at what these flanges bring to your routine, from the way they sit against the breast to how they endure daily hygiene tasks. Consider these as possibilities to enhance your setup rather than guarantees of results, and choose based on your measurements and preferences.
