Maymom 18 mm Flange Insert (Blue) – Compatible with Elvie & Medela Shields

Discover the Maymom 18 mm Flange Insert in blue

When you want a more tailored pumping experience without changing your entire shield setup, this Maymom insert offers a practical, non-invasive option. The 18 mm size is designed to slide inside many 24 mm shields, creating a snugder, more comfortable tunnel while you pump. The blue color makes it easy to spot in your kit, and the silicone material is chosen for durability and everyday use.

What’s included

• Two 18 mm silicone inserts (short version) — ready to use with compatible shields
• Designed to fit inside 24 mm Elvie Single/Double shields and Elvie Stride Cup (24 mm)
• Turns a 24 mm nipple tunnel into an 18 mm passage for a potentially closer feel
• Broad compatibility with popular brands and shields including Momcozy S9/S10/S12, LegendaryMilk, Tsrete wearables, and more
• Works with Medela PersonalFit Flex 24 mm, Motif Luna 24 mm, Ameda Mya 24 mm and Ameda Mya Pro 24 mm
• Maintains compatibility with most hands-free bras when the insert is used inside the shield
• Snug, trim-free design with available sizes ranging from 13 to 21 mm (this model includes 18 mm)
• BPA-free, food-contact grade silicone — safe for daily use by moms and babies

Compatibility and versatility

This insert is crafted to work as a smart adapter across a spectrum of popular brands. If your current shield is 24 mm, the 18 mm insert can help tailor the tunnel to a size that feels more secure, while preserving the integrity of your pumping setup. The combination of a stable fit and the broad shield compatibility can support your existing pumping routine without requiring you to invest in a new shield system.

Fit, use and care

Tips for use: place the insert inside a 24 mm shield before pumping. The design is intended to provide a snug fit without needing to trim or modify the insert. Keep the silicone clean between uses with mild soap and water, and allow it to air dry completely to maintain material quality.

Materials and safety

Constructed from BPA-free, food-contact grade silicone, the insert emphasizes a safe, durable option for everyday pumping. While designed for close compatibility with multiple shields, always check fit and comfort with your specific setup. This is a non-original part intended for compatibility and versatility, not a guaranteed replacement for any manufacturer.

Real-world use scenarios

• Adjusting a slightly larger shield to a narrower tunnel for a potentially more secure feel during pumping sessions
• Using with a hands-free bra that accommodates 24 mm shields to maintain a streamlined pumping setup
• Having a blue, clearly identifiable insert in your kit for quick swaps during busy days

Why choose Maymom

Maymom offers a flexible adapter option that broadens shield compatibility without requiring a full shield replacement. The 18 mm insert can be a practical addition for those exploring different pump configurations while keeping a focus on safety and everyday use.
