Compatibility & What’s Included

The kit is compatible with Momcozy S9, S12, S9 Pro, and S12 Pro models as well as TSRETE electric pumps. It includes six essential parts—the diaphragms and duckbill valves you rely on to maintain proper fit and function.

• Six replacement parts in total: diaphragms and duckbill valves
• Designed for S9/S12 Pro and related Momcozy pumps
• Simple swap-in design to refresh your pump between cleanings

Materials & Safety

All parts are BPA-free and made from food-grade silicone. They are soft to the touch, odorless, and designed to feel comfortable during use, while helping you keep a hygienic pumping setup.

Care, Cleaning & Maintenance

• Wash after each use with warm soapy water
• Suitable for steam cleaning, boiling water, or microwave steam bags

Inspect seals regularly and replace parts based on your installation and suction status to help preserve performance.

Why Replace & How It Helps

The diaphragm helps the pump maintain a reliable seal to reduce leakage, while the duckbill valve supports efficient milk drainage toward the container bottom. Regular replacements can help maintain suction quality and overall pump efficiency.

Real-Life Use & Tips

Whether you’re juggling a busy day, commuting, or handling nighttime feeds, these parts offer a practical refresh that fits your routine. Pair with proper cleaning and drying practices to extend use between replacements.

• Consider replacing every 2–3 months or as suction changes
• Store parts dry and clean between uses to avoid odor buildup
