NENESUPPLY 21mm Flange Breastshield – Lansinoh Pump Compatible Replacement

Overview

Meet the NENESUPPLY 21mm flange breastshield, a breast shield designed to work with popular Lansinoh pump parts and the Signature Pro, SmartPump, and Manual models. This replacement 21mm flange offers an alternative option with several sizes and a thoughtful design that emphasizes comfort and usability.

Comfort and fit

Comfort and fit are central. The longer tunnel and smooth angle are described as a comfortable design, particularly for users who pump for longer sessions or who prefer a deeper reach. The product is available in five sizes—17mm, 19mm, 21mm, 24mm, and 28mm—so you can try different options to find a snug, gentle fit that suits your nursing surface and pumping rhythm. Because the flanges are not original Lansinoh parts, they offer a cost-effective alternative while maintaining compatibility with the pump ecosystem through the provided connectors.

Compatibility

Compatibility is a key benefit. These flanges are designed to work with Lansinoh flange connectors and with Signature Pro, SmartPump, and Manual pumps. They can also be used with most hands-free bras that accept standard flange attachments, helping you set up a convenient pumping routine when you are multitasking at home or on the go.

Care & materials

Care and materials are addressed in the design. The shields are detachable two-piece units, intended to be easy to clean and dishwasher safe, with BPA and DEHP-free materials for a safer, simpler cleanup after pumping sessions. The two-piece design also supports flexible cleaning and easy storage for busy families.

What you get

What you get. A set that includes the NENESUPPLY 21mm flange in whichever configuration you choose, plus the confidence of a compatible alternative designed to fit within a busy pumping setup. This description reflects the noted benefits: size variety, a longer tunnel for fit variety, compatibility with common pumps and connectors, ease of cleaning, and safe materials. While outcomes can vary, many users find a comfortable fit is achievable with the range of sizes and the ergonomic design.
