Overview

The Fukaisu 12-piece replacement kit is designed for popular eufy breast pumps, including S1 Pro, S1, E10, and E20. It bundles four silicone diaphragms with eight duckbill valves to refresh your setup when parts show wear, helping maintain smooth pumping sessions without interruption.

What’s Included & Compatibility

This kit provides four silicone diaphragms and eight duckbill valves, engineered to fit the listed eufy models. Important note: Fukaisu is an independent brand and is not sponsored by or affiliated with eufy.

Premium Materials

The diaphragms are crafted from high-quality silicone that is soft and skin-friendly, yet durable enough for frequent use. They resist deformation and discoloration, staying reliable through many pumping sessions.

Thoughtful Design

The duckbill valves direct breast milk into the collection container and are designed to stay closed when not pumping, helping to prevent backflow. The flexible silicone diaphragm provides steady suction for more consistent expression during each session.

Ease of Cleaning

After use, rinse with warm water and air-dry. Avoid scrubbing with hard brushes or steel wool; a soft sponge or fingertips is best for keeping surfaces smooth for the next use.
