Maymom Bellababy Pump Parts Kit 21mm — Double Electric & MiniO Compatible

Overview

Maymom offers a thoughtfully designed set of pump parts that work with Bellababy Double Electric and Bellababy MiniO systems. The kit centers on a 21mm detachable flange, paired with connectors and valves to support a secure fit, steady suction, and straightforward cleaning. This collection is built to sit comfortably in everyday pumping routines, with attention to fit, assembly, and material safety.

What’s included

• 21mm detachable flange (x2)
• Wide-mouth base connector with membrane and cap (x2)
• Duckbill valve (x2)
• Shield/flange (x2)

Note: Tubing and bottle are not included in this kit. The 21mm detachable flange is suggested for mothers with nipple diameter around 19–20 mm after pumping.

Size, fit, and real-world use

Choosing the right flange size can influence comfort and pumping efficiency. Maymom recommends measuring nipple diameter after a pumping session and selecting a size that is 1–2 mm larger than that measurement. The two-piece flange design is easy to assemble, disassemble, and clean, and it fits most hands-free pumping bras on the market.

• Two-piece construction simplifies assembly and cleaning
• Detachable flange design supports flexible setup with Bellababy pumps
• Widely compatible with common hands-free pumping bras and configurations

In daily use, the kit’s components support a steady seal and smooth transition between parts, which can help you keep routine pumping at home or on the go. Remember, this is a replacement kit intended to complement Bellababy pumps, not an OEM Bellababy part.

Care, safety, and compatibility

• Parts are BPA/DEHP free and packaged in retail-ready packaging
• Materials comply with EU and USA FDA guidelines for items that contact food
• All items are designed to perform on Bellababy Double Electric and MiniO pumps

To maintain quality, the kit parts can be cleaned with boiling water or steam. Regular inspection and proper cleaning help preserve seal integrity and long-term performance.
