These 12-piece duckbill valves and silicone diaphragms serve as replacement parts designed for compatibility with eufy wearable breast pump models including E10, E20, S1, and S1 Pro.

Crafted from flexible, food-grade silicone, the valves and diaphragms offer a soft yet resilient texture that maintains structural integrity through repeated use. The duckbill valve design features a slit opening that opens under suction and closes tightly to prevent backflow, ensuring consistent vacuum pressure during pumping sessions. The silicone diaphragms work in tandem with the valves to regulate airflow, contributing to the pump’s overall efficiency and reliability. The components are manufactured with precise dimensions to match the original specifications of the compatible eufy pumps, providing a snug fit that minimizes air leaks. This tight seal is essential for maintaining optimal suction strength, which directly affects milk expression effectiveness. Regular replacement of these parts is recommended to preserve pump performance, as silicone can naturally degrade over time with frequent washing and sterilization. The set includes twelve pieces, offering a practical supply for extended use or multiple pump units. In terms of material quality, the silicone used is non-porous and resistant to odors, making it suitable for contact with breast milk. The surface is smooth to the touch, which facilitates easy cleaning and reduces residue buildup. These components are designed to withstand repeated boiling or steam sterilization without losing flexibility or shape. Their lightweight construction does not add noticeable bulk to the breast pump assembly, preserving the portability and discretion that wearable designs offer. The 12-pack configuration provides a cost-effective solution for users who need periodic replacements or prefer to have backups on hand. Each duckbill valve and diaphragm is individually formed to ensure consistent opening and closing action, which supports steady milk flow. While not a consumable that requires daily change, replacing these parts every few months (depending on usage frequency) can help maintain the pump’s original suction performance and hygiene standards. The components are compatible only with the specified eufy models, so verifying compatibility before purchase is advisable. This replacement set addresses the need for affordable, reliable maintenance parts for breast pump users. The silicone material offers a balance of durability and flexibility, allowing the valves to function effectively without becoming too stiff or too loose. By replacing worn components with these silicone parts, users can extend the usable life of their breast pump and avoid the higher cost of purchasing a new pump system. The product focuses on delivering functional performance without unnecessary embellishments, making it a straightforward accessory for routine pump care.
