eufy Breast Pump Duckbill Valves (4-Pack) – E10, E20, S1 & S1 Pro

Small components. An essential role in your pumping routine.

Keep your breast pump working as intended with the eufy Duckbill Valves (4-Pack), designed for compatible eufy Wearable Breast Pump E10, E20, S1 and S1 Pro models.

These replacement duckbill valves are important components within the breast pump’s milk collection system. Their flexible, one-way valve design allows expressed breast milk to pass into the collection container while helping prevent milk from flowing backwards.

Whether you’re replacing worn valves, maintaining your existing breast pump or keeping spare accessories available, this convenient four-pack offers a practical way to keep your pumping equipment ready for everyday use.

Essential One-Way Valve Function

Duckbill valves play an important role in the operation of a wearable breast pump.

During pumping, the flexible valve opens to allow expressed breast milk to enter the collection container and closes to help prevent milk from flowing back through the collection pathway.

Correctly functioning valves also help maintain the intended pressure conditions within the pumping assembly.

Key benefits:

• Supports the breast pump’s milk collection system
• Allows expressed breast milk to flow into the collection container
• Helps prevent milk from flowing backwards
• Supports the intended operation of the pumping assembly
• Provides replacement components for regular breast pump maintenance

Compatible with eufy E10, E20, S1 & S1 Pro

These replacement duckbill valves are intended for use with the following eufy wearable breast pumps:

• eufy Wearable Breast Pump E10
• eufy Wearable Breast Pump E20
• eufy Wearable Breast Pump S1
• eufy Wearable Breast Pump S1 Pro

Designed as replacement accessories, they provide a practical solution for maintaining your existing pumping equipment without purchasing an entirely new breast pump.

Please note: Compatibility with other eufy breast pump models should not be assumed.

Convenient 4-Pack – Keep Spare Valves Ready

Each pack contains four replacement duckbill valves, making it easier to maintain your pumping equipment and keep spare components available when needed.

Duckbill valves are flexible components that may experience wear through repeated pumping and cleaning.

Having replacement valves ready can be particularly convenient for parents who express breast milk regularly.

Ideal for:

• Replacing worn or damaged duckbill valves
• Keeping spare pumping accessories available
• Maintaining compatible eufy wearable breast pumps
• Refreshing frequently used milk collection components
• Supporting regular milk expression routines

Help Maintain Your Breast Pump’s Performance

Duckbill valves are designed to open and close during the pumping cycle.

Over time, repeated use and cleaning may cause flexible valve components to lose their original shape or sealing ability.

A damaged, stretched or incorrectly fitted valve may affect the operation of the breast pump’s milk collection and suction system.

Regular inspection and timely replacement can help maintain the intended operation of your pumping equipment.

Signs that a duckbill valve may need replacing include:

• Visible tears, cracks or splits
• Distortion or stretching
• Valve lips that no longer close properly
• Difficulty fitting the valve securely
• Unexpected changes in pumping performance
• Visible wear or deterioration

Important: Reduced suction or pumping performance may have several causes. Always inspect the complete pumping assembly and follow the manufacturer’s troubleshooting guidance.

Practical Replacement Without Replacing Your Pump

Maintaining individual breast pump components is a practical way to extend the useful life of your existing equipment.

Rather than replacing the complete breast pump when a valve becomes worn or damaged, you can replace the affected component with a compatible accessory.

The eufy Duckbill Valve 4-Pack provides a convenient replacement solution for compatible E10, E20, S1 and S1 Pro wearable breast pumps.

Easy Maintenance for Everyday Pumping

Breast pump duckbill valves should be handled carefully and cleaned according to the manufacturer’s instructions.

Because they form part of the milk collection pathway, appropriate cleaning and maintenance are essential.

Recommended care:

• Wash your hands before handling breast pump components
• Clean valves according to the manufacturer’s instructions
• Follow approved sanitising procedures
• Avoid stretching or pulling the flexible valve opening unnecessarily
• Inspect regularly for tears, distortion or damage
• Allow components to dry as instructed before storage
