Maymom 19mm 2x One-Piece Breastshield with Valve & Membrane for Medela Pumps – Extra Small, Clear

Overview

The Maymom 19 mm 2x One-Piece Breastshield kit is built for smaller pumping diameters, offering a clear, non-detachable shield with an integrated valve and membrane. The two-shield set is designed to be easy to assemble, wash, and reuse, turning routine pumping sessions into a smoother, more predictable ritual. If you measure your nipple diameter around 17-18 mm after pumping, this 19 mm size is intended to sit comfortably with a thin, soft edge that helps seal without excessive pressure. The kit includes two complete shields, two valves, and four membranes, so you’re ready for efficient sessions from setup through cleanup.

Fit and Medela compatibility

Designed to accommodate smaller nipple diameters, these shields pair with many Medela pumps—such as Pump in Style, Lactina, Symphony, Swing, and Mini Electric—providing a compatible, streamlined option. Some Medela models are not supported, including FreeStyle, Swing Maxi, Sonata, Harmony, and MaxFlow Pro Pro+. If you’re unsure about compatibility, checking your pump model against the included notes can help.

Safety, materials, and regulatory details

Maymom emphasizes safe materials and clear regulatory context. The shields are manufactured from BPA-free and DEHP-free materials and are steam-safe for high-temperature cleaning. The kit is registered as a medical device with the US FDA (No. D192499), and it adheres to recognized standards for products that contact fluids and skin. For transparency, external test reports are posted online for reference, allowing you to review performance data before purchase.

Packaging, authenticity, and care

The set arrives in retail poly-bag packaging, sealed by Maymom to preserve freshness and integrity until first use. While it is compatible with Medela pumps, these are Maymom parts and not original Medela components. Regular cleaning and proper sterilization help maintain hygiene and performance across uses.

Size options

In addition to the 19 mm shield in this kit, Maymom offers a broad size range to match evolving pumping needs, including 13, 15, 17, 21, 24, 25, 26, 27, 29, 30, and 36 mm options. If you’re experimenting with fit, starting with the 19 mm size can be a practical choice while exploring other sizes as needed.
