What’s included

Material & build quality

Crafted from soft, skin-friendly silicone, these parts stay flexible yet durable. They resist deformation, discoloration, and frequent use, helping you rely on them session after session.

Design features that support your routine

• The duckbill valve guides breast milk into the collection container and stays closed when not pumping, helping minimize backflow concerns.
• The flexible silicone diaphragm provides strong, stable suction for more efficient expression while remaining comfortable to use.

Cleaning & maintenance

Cleaning is quick and straightforward: rinse with warm water after pumping, then air-dry. Avoid scrubbing with hard brushes or steel wool to preserve the silicone’s surface and lifespan.
