Milkflow Replacement Parts Set - 2 Diaphragms + 4 Duckbill Valves, Compatible with Elvie Breast Pump Parts, One-Way Valves & Diaphragm Inserts,

This set includes 2 diaphragms + 4 duckbill valves for shoppers looking for Elvie replacement parts / Elvie breast pump parts. Diaphragms support sealing/pressure transfer; duckbill valves control one-way flow. Please compare your pump model and original part shape for the right fit Worn diaphragms or softened valves can make suction feel inconsistent—same level, more effort, more re-adjusting. Replacing both parts helps re-seat the seals for smoother starts and steadier sessions, ideal for commute days and quick office breaks Duckbill valves are designed for one-way flow—the slit stays closed when not pumping to help reduce backflow mess. Keep a spare in your bag for quick swaps if the valve feels soft or sealing drops, so pumping stays manageable on the go The 2 diaphragm + 4 valve pack is built for smart rotation—keep one set at home and one in your work bag. If a valve warps or a diaphragm stops sealing well, you can swap fast instead of pushing through a frustrating session. For frequent pumpers, spares mean fewer interruptions and less stress If suction drops or flow feels off, check the duckbill tips for softening/tears and the diaphragm edge for curling—these are common wear parts, and replacing them first is a quick fix step. After installation, re-check alignment and tight seals to avoid air leaks
