Gotocut Flange Inserts 17mm & 19mm – 4PCS, BPA-Free Silicone, Fits Spectra/Elvie/Medela/Willow

Discover Gotocut Flange Inserts, a soft, transparent silicone accessory designed to tailor your wearable breast pump setup. Built to work with a wide range of popular flange sizes, including many 24mm/25mm shields, these inserts put you in control of fit while keeping portability and ease of use at the forefront. The result is a calmer, more personalized pumping experience that can adapt as your routine changes.

Two core sizes, broader compatibility

The set centers on essential 17mm and 19mm inserts, chosen to accommodate common sizes while remaining adaptable to a broad selection of brands such as Spectra, Elvie, Medela, Willow, Go, Bellababy, MOMMED, and more. The inserts are made from BPA-free silicone, and you can sanitize them using steam, boiling water, or microwave-steam bags between uses for quick reusability.

What makes this set practical

• 8 size options to explore your actual size, helping you discover a comfortable fit over time.
• A practical 4-piece subset for everyday use while you learn your best size.
• Lightweight, clear inserts let you observe placement and sizing during pumping.

Comfort-focused design with realistic expectations

These inserts resize a flange for the right size, aiming to reduce nipple rubbing and strain by creating a more tailored seal. This is not medical advice, and results can vary depending on your pumping setup and routine.

Care and safety

• Made from food-grade silicone that’s BPA-free and easy to clean.
• Supports safe sanitation through steam, boiling water, or microwave-steam methods between sessions.

Real-life use scenarios

Picture swapping between sizes through a busy day—a quick adjustment during morning prep, a quieter evening session, or a shift after you settle into a rhythm. The transparent design helps you monitor fit and placement with each trial, making it easier to identify what feels most comfortable across occasions.
