IVARONAL 12pcs Duckbill Valves & Silicone Diaphragms for Lansinoh, eufy S1 Pro, S32 Pump Parts

Overview

IVARONAL delivers a practical 12-piece replacement kit designed to support a wide range of popular breast pump systems. The set pairs 10 duckbill valves with 4 silicone diaphragms, providing a ready-to-use solution for ongoing maintenance of compatible pumps. Rather than replacing an entire assembly, you can refresh the critical components that influence milk flow and suction, all with an emphasis on ease, reliability, and cost-efficiency.

Engineered with real-world pumping in mind, these parts are sized to fit many common valve housings and diaphragms. This kit is handy for households that operate multiple pump models or switch between configurations. It is presented as a practical upgrade for maintaining a smooth pumping routine and clean equipment life, rather than a guaranteed outcome.
