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

Max Suction and Anti-Backflow: A fresh diaphragm not only delivers consistent suction for efficient pumping, but also safely blocks milk from entering the motor, keeping your pump clean and damage-free.

Baby-Safe Silicone: Crafted from premium, food-grade silicone that is BPA-free and incredibly soft. Rigorously tested to withstand repeated daily use and high-temperature sterilization without losing its shape.

Easy to Install and Clean: Easy to install, remove, and clean. Simply wash with warm soapy water or sterilize it alongside your other pump parts for hassle-free prep.

Replacement Schedule for Best Results: To maintain strong suction and hygienic pumping, we recommend replacing the diaphragms every 2 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.
