beaina Wearable Breast Pump Parts - Duckbill Valve, 24mm Flange, 2 Sets, Compatible with Lansinoh Discreet Duo, Mammanuwa, Nuliie S32

Overview

Beaina’s wearable breast pump parts arrive as a practical two-set bundle designed to work with popular pumps such as Lansinoh Discreet Duo, Mammanuwa, and Nuliie S32. The kit includes a duckbill valve, a silicone diaphragm, a 24mm flange, and a milk collector cup. This combination is built to support comfortable, efficient sessions, with an emphasis on fit, sealing, and easy care for busy days.

Key benefits and design details

• Leak-resistant design achieved by the silicone diaphragm and soft silicone breast shield that help seal around contours during pumping.
• One-direction flow through the duckbill valve reduces backflow and keeps sessions cleaner.

Safety, comfort, and materials

All parts are made from food-grade silicone and BPA-free, prioritizing a gentle touch against the skin and reliable durability for daily use.

Capacity and practicality

The milk collector cup holds up to 150 ml (5 oz), supporting mid-length pumping sessions without the need for frequent pauses to empty.

Ease of use and cleaning

• Fewer parts mean simpler assembly, quicker transitions between pumping tasks, and easier cleaning between uses.
• The two-set bundle provides ready-to-go backups so you can swap parts without downtime.

Flange sizing guidance

Flange size matters for comfort and pumping efficiency. Start with your usual size and watch for signs like discomfort or reduced suction; adjusting flange size can improve fit and performance.

Real-life scenarios

Designed for on-the-go use—commutes, work breaks, or nighttime sessions—these parts offer flexibility and peace of mind when you’re away from home. The compact two-set bundle travels well in a bag and can be swapped between compatible pumps quickly.
