afontoto Flange Insert 15mm for S9/S12 Wearable Breast Pumps – 2-Pack, BPA-Free Silicone

Meet afontoto Flange Insert 15mm

Designed for use with S9, S12, S9Pro, and S12Pro wearable breast pumps that use 24 mm shields, this 15mm insert threads into the existing flange path to create a narrower opening. The silicone is soft to the touch, with smooth edges for comfortable insertion. The insert is transparent for easy inspection between sessions.

Why choose a 15mm insert

Not every pumping session is the same. Some days you may prefer less width to reduce rubbing or to accommodate changing nipple shape during milk expression. This insert provides a narrower tunnel without replacing your entire shield, giving you a more tailored fit during use. This is a potential benefit some parents notice when experimenting with different sizes.

Key benefits

• Flexible, BPA-free silicone that’s safe for skin contact
• Compatible with 24mm shields and milk collectors, expanding your options
• Reduces the effective diameter to 15mm for a snug, comfortable feel
• Easy to clean and sanitize—works with warm soap and water and steam or boiling methods
• Two-piece, transparent pack provides a simple replacement or backup
• Designed to complement wearable breast pumps and maintain a steady pumping setup

How to use and care

• Wash the insert after each use with warm soapy water
• Rinse thoroughly and allow to air dry before next use
• During pumping, ensure the nipple sits comfortably and does not rub or squeeze inside the tunnel
• For sanitizing, the material tolerates steam, boiling water, or microwave steam bags

Quality and safety

All AFONTOTO pump parts that contact breast milk are BPA-free. The 15mm insert is silicone, non-odor, soft to the touch, and designed as a durable accessory for busy parenthood. The two inserts come in a transparent finish for easy quick checks during maintenance.
