Hranio Flange Insert 17mm – 8pc Flange Sizing Kit for Spectra, Medela, Momcozy & More

Meet the Hranio Flange Insert 17mm, an 8-piece silicone sizing kit designed to tailor flange fit across different pumping moments. Crafted from food-grade silicone and free from BPA, these inserts are built to withstand regular cleaning and sterilization. The set adapts many 24mm flange systems to a smaller inner channel, offering a comfortable, streamlined experience during expression.

Versatile compatibility

Designed to work with a wide range of popular pumps and flange shields, the kit supports brands such as Spectra, Medela, Momcozy, Willow, Elvie, and more. Note: it is not intended for 27mm shields.

• Fits most 24mm flanges, reducing to 17mm for a snug, comfortable fit
• Broad compatibility across Spectra, Medela, Momcozy, Willow, Elvie, and other major brands
• Helps accommodate changes in nipple size during lactation without swapping whole flanges

Care and safety you can count on

• BPA-free silicone keeps contact with milk safe for everyday use
• Easy cleaning: wash with warm soap, rinse well, and sterilize by boiling or steaming at about 100°C
• Inspect fit during pumping; if rubbing occurs, switch to a different size insert

In real-life terms, a simple insert can transform comfort and alignment during pumping. The soft silicone edge feels gentle against skin, while the precise inner diameter supports a controlled channel for milk expression. While results vary, using the right size may contribute to a smoother pumping rhythm and a more comfortable session.
