IVARONAL Upgraded 14mm Flange Insert with Pull Tab & Triangle Cutout – 6 Pack, 24mm Shield Compatible

Enhance your pumping experience with a flexible, comfortable fit

IVARONAL presents the Upgraded 14mm Flange Insert with Pull Tab and Triangle Cutout, designed to adapt standard 24mm shields to a friendlier, more individualized fit. Compatible with a wide range of popular pumps—Momcozy, Spectra, Medela, eufy, TSRETE, Elvie, Lansinoh, and more—this 6-pack gives you multiple sizes to match your changing needs during your breastfeeding journey. Instead of one-size-fits-all, you can fine-tune the shield interior to your tunnel and aid a smoother pumping session.

What sets this insert apart is the triangle-cutout at the bottom of the milk-tunnel and a slightly tapered end. The design is intended to guide milk toward the bottle more easily and to create a secure, comfortable fit inside the flange. While individual results vary, many users appreciate the noticeably softer touch of the silicone and how the tunnel feels less crowded, which can contribute to a more relaxed pumping experience.

Key benefits and practical use

• 15mm to 24mm compatibility range in mind: Specifically sized to work with 24mm shields found on many pumps, offering a practical upgrade without changing your main equipment.
• Triangle-cutout bottom for improved milk transfer: A tapered, triangular design aims to support a steady flow toward the bottle while keeping the fit secure.
• Soft, food-grade silicone (BPA-free): The material is gentle to the touch, helping reduce irritation while pumping.
• 10-size options (13–22mm): A wide range ensures you can adapt as your baby grows or as your comfort needs change.
• Pull tab for easy insertion and removal: A simple grip makes changing sizes quick and convenient between sessions.
• Frosted, transparent finish for visibility: See-through design makes alignment and cleaning straightforward.

Care and maintenance

• Easy sanitation: The inserts are designed to be cleaned and sanitized, including compatibility with boiling-water sterilization.
• Replacement guidance: For optimal performance, consider renewing inserts every couple of months based on usage.

Compatibility note

The kit is designed for 24mm shield compatibility across many popular brands. It is not intended for 27–28mm shields. If your setup uses a 24mm shield, this set can offer a customizable, cushioned fit while keeping your existing pump configuration.

With the IVARONAL 14mm flange insert set, you gain flexible sizing, a distinct triangle-cutout design, and a comfortable silicone feel—offering a potential upgrade path that respects your routine and needs without promising specific results. Use as a practical option to explore a more tailored pumping experience.
