Silicone Duckbill Valves Diaphragms 12PCS for Eufy E10 E20 S1 S1 Pro Breast Pump Replacement Wearable Nursing Accessories

Precision-engineered silicone duckbill valves and diaphragms in a 12-piece set, designed as replacement components for eufy wearable breast pumps including models E10, E20, S1, and S1 Pro. Each valve-diaphragm pair ensures a secure, leak-free seal that maintains consistent suction performance, supporting efficient milk expression. The optimized duckbill structure prevents backflow, directing milk flow one-way into the collection bottle to protect internal pump components from moisture damage and maintain hygiene. Made from food-grade silicone, these parts offer softness and durability for long-term use while remaining compatible with regular cleaning routines. They can be easily washed with warm soapy water or sanitized through boiling or steam sterilization for 5–10 minutes, ensuring safe usage between sessions. Ideal for nursing mothers relying on hands-free pumping, these accessories enhance comfort, reliability, and overall pump efficiency. Regular replacement helps sustain peak performance, making them essential maintenance items for daily breastfeeding support.
