6pcs Breast Pump Parts for eufy S1 Pro/S1/E10/E20 | Fukaisu Diaphragms & Duckbill Valves Replacement

Fukaisu Replacement Parts for eufy Pumps

Busy days demand reliable, ready-to-use replacements. Fukaisu presents a 6-piece kit designed for eufy pumps, including 2 silicone diaphragms and 4 duckbill valves. While this product is not sponsored by or affiliated with eufy, the parts are crafted to complement common eufy models such as S1 Pro, S1, E10, and E20. Expect a practical blend of comfort, durability, and ease of use that can help you keep expression moments smooth and consistent throughout your day.

What’s Included

• 2 silicone diaphragms — soft, skin-friendly silicone built for a comfortable feel during expression.
• 4 duckbill valves — designed to direct milk into the collection container while staying closed when not pumping.

Designed for Reliable Expression

The parts are designed to pair with eufy hardware, supporting a seamless swap when you need replacements. The duckbill valve features a slit that helps guide milk into the bottle, and it stays closed when not pumping to help minimize backflow. The flexible silicone diaphragm provides strong and stable suction for more efficient expression across pumping sessions, delivering a balanced combination of performance and comfort.

Materials, Durability, and Hygiene

Constructed from high-quality silicone, these components resist deformation, wear, and discoloration, even with frequent use. The soft, skin-friendly material is built for repeated handling, making it a practical choice for long-term replacement needs. Durable construction meets everyday pumping demands without compromising on feel or reliability.

Easy Cleaning and Care

• After use, rinse with warm water and allow to air dry; avoid scrubbing with a hard brush or steel wool.
• Clean with a soft sponge or your fingertips to protect the silicone’s surface and longevity.

Practical Use and Tips

Having a spare kit on hand reduces downtime during busy days or trips. Replacement parts like these can help you maintain consistent expression routines, especially when you’re on the go. Always confirm model compatibility (S1 Pro, S1, E10, E20) to ensure a proper fit and a smooth pumping experience. This kit emphasizes readiness and reliability for daily use rather than guaranteeing any outcome—your routine remains flexible and under your control.
