IVARONAL Flange Inserts 15mm – 6PCS for 24mm Shields (Momcozy, Medela, Spectra & More)

Better Fit for More Comfortable Pumping

IVARONAL Flange Inserts in a precise 15 mm size offer a flexible add-on for wearable breast pump setups. This six-piece set is designed to help you tailor shield diameter to your needs, so sessions feel more natural and less tight. By promoting a snug, breathable seal, these inserts aim to reduce rubbing and discomfort while you express.

Choose Exact Size for Your Pumping

With a broad size range from 12 mm to 22 mm, you can fine-tune the tunnel diameter to suit your body and your flange. During pumping, monitor how your nipple sits inside the tunnel; a comfortable alignment should avoid rubbing or being squeezed. The goal is a secure fit that supports steady expression without strain.

• Observe nipple appearance and tunnel feel during pumping to avoid rubbing
• Adjust size for a balanced seal that reduces pressure hotspots

Wide Compatibility Across Brands

The inserts are built to work across a variety of popular wearable pumps, including Momcozy, Medela, Spectra, Lansinoh, and more. They target 24 mm shields and are not designed for 27 mm shields, so be sure to match your equipment.

• Compatible with Momcozy, TSRETE, Spectra, Medela, Lansinoh and many models
• Not suitable for 27 mm shields

Make Pumping More Efficient with the Right Fit

Reducing the 24 mm tunnel to a precise, comfortable size can help create a snug seal, potentially easing milk expression and reducing discomfort during long sessions. While experiences vary, a better fit may support a steadier pumping rhythm for some users.

Safe, Skin-Friendly Materials

Crafted from food-grade silicone, these inserts are BPA-free and odorless. The soft, skin-friendly surface aims to minimize irritation and provide a gentle touch against the skin while you pump.

Easy to Install and Clean

Installation and removal are simple, allowing quick setup between sessions. After pumping, wash with warm soapy water and rinse well. They can be sanitized with steam, boiling water, or microwave-safe bags. Replace inserts if they become deformed or yellowed over time.
