Eufy Home Collection Duckbill Valves (4-Pack) for Breast Pump S2 / S2 Pro Breast Pump Accessories, Hands-Free Pump Parts

Perfect Compatibility: Exclusively designed to be fully compatible with eufy Wearable Breast Pump S2 and S2 Pro.

Secure Anti-Backflow Design: Prevents milk from backing up and ensures strong suction. The precision slit stays tightly closed between pumps, safely directing every drop into the container.

Food-Grade Soft Silicone: Made from durable, BPA-free, food-grade silicone, it is completely safe for breast milk contact. The snug fit offers comfort and efficient pumping.

Easy to Clean and Sterilize: Wash with warm soapy water after every use. Gently clean the delicate valve tips with the included cleaning brush—avoid hard brushes to prevent damage. For deep cleaning, safely sterilize in boiling water or steam (up to 212°F / 100°C) for 5 – 10 minutes.

Replacement Schedule for Best Results: To maintain strong suction and hygienic pumping, we recommend replacing the duckbill valves every 1 to 3 months, or sooner if you notice a drop in output or visible wear and tear.

Guaranteed Reliability and Quality: Purchase with confidence. All original eufy breast pump accessories are backed by a 90-day limited manufacturer’s warranty and reliable customer support for your peace of mind.
