Yeabetter Flange Sizing Kit — 20Pcs 13–22mm for 24mm Breast Pumps

New moms often face a common challenge: finding a comfortable, effective flange size for breast pumping. Yeabetter's Flange Sizing Kit is designed to simplify that decision, pairing a comprehensive range of sizes with practical tools that fit into a busy day. With 20 flange inserts in 10 sizes (13–22 mm) in two of each size, plus a nipple measurement card and a silicone cleaning brush, this kit keeps size options within easy reach while you adjust to your rhythm as a new parent.

What you get in the 3-in-1 kit

• 20 silicone flange inserts in sizes 13, 14, 15, 16, 17, 18, 19, 20, 21 and 22 mm (two of each)
• Nipple measurement card to help you pick a precise fit
• Silicone cleaning brush for quick, effective cleaning after use

Designed for common 24 mm pumps

The inserts are intended to fit most 24-25 mm wearable pumps, helping to reduce the nipple tunnel to a more comfortable size. The kit notes that 27-28 mm shields are not compatible.

Comfort, efficiency and flexibility

Soft silicone is gentle on the skin, and multiple sizes let you tailor the fit as your needs evolve. While individual results vary, the right size can support a smoother pumping session and a more comfortable experience overall. The range helps you explore fitting options without guesswork.

Safety and upkeep

All inserts are made from food-grade silicone and are BPA-free. They are dishwasher safe for easy sanitation. The kit includes a cleaning brush, and Yeabetter recommends cleaning inserts after each use and replacing them approximately every two months to maintain performance.

How to use

Start with the nipple measurement card to determine a likely size, then try inserts across the mid-range sizes. If needed, adjust to larger or smaller sizes to find a more comfortable fit during pumping.

Care and compatibility notes

Keep the kit clean and dry between uses. Check your model's specifications if you are unsure about fit, and store inserts in a clean, dry place to prolong silicone life.
