IVARONAL Two Full Milk Collector Cup Sets for Momcozy S12 Pro/S9 Pro • 19mm Flange Replacement Pump Parts

Overview

IVARONAL presents two complete sets of milk collection parts designed for Momcozy S12 Pro and S9 Pro breast pumps. These are replacement parts (not original Momcozy accessories) built by IVARONAL to support ongoing pumping routines. Each set centers on a 19mm flange and a comprehensive trio of components to help maintain a smooth milk collection process, including a duckbill valve, silicone diaphragm, linker, and two milk collector cups. The design emphasizes comfort, clean transfer, and dependable backflow control during use.

What’s in the box

• Two 19mm flanges for compatible Momcozy S12 Pro/S9 Pro setups
• Two milk collector cups designed for stable milk transfer
• Two duckbill valves that support one-way milk flow
• Two silicone diaphragms that form a soft, flexible seal
• Two linkers for secure assembly with the pump parts
• All parts are BPA-free and made from food-grade silicone, ready for reuse after cleaning

Key benefits and how it may fit your routine

The kit offers a soft-touch feel and thoughtful engineering to help reduce perceived soreness and swelling during pumping sessions. While individual results vary, the materials are chosen for comfort against the skin and a gentle seal that assists with steady milk transfer. The closed-system, dual-channel design separates gas from milk, aiming to minimize leaks and keep the motor area clean, which many users appreciate during longer pumping sessions.

Design and performance highlights

• Closed system with anti-backflow features to help prevent spills and keep milk moving in one direction
• Silicone diaphragm design minimizes gaps on the top, supporting a snug fit with reduced leakage risk
• Soft silicone shields that rest against the breast for comfortable contact during use
• Reliable components packaged as two complete sets for use with two pumping sessions or shared equipment

Care and compatibility

All parts are BPA-free and crafted from food-grade silicone, designed for easy cleaning after use. Wash with warm, soapy water and rinse well. The kit recommends heating via boiling water or steam at ≤100°C (212°F) for 5–10 minutes between uses to maintain hygiene and pliability. Before purchasing, confirm compatibility with Momcozy S12 Pro/S9 Pro models, as these parts are not original Momcozy accessories and are not intended for S9/S12 models.

Usage tips

• Inspect all seals and valves for wear before each use
• Assemble parts securely to maintain suction and reduce noise during pumping
• Allow parts to dry completely before reassembling to prevent odors or residue buildup
