LOZAEVE 19mm Silicone Flange Insert – Reduce 24mm to 19mm for Medela, Spectra, Momcozy & More | BPA-Free

Customize Your Shield Fit with LOZAEVE 19mm Silicone Flange Insert

The LOZAEVE 19mm silicone flange insert is designed to adapt a standard 24mm shield to a smaller, more comfortable tunnel. Made from BPA-free silicone, it offers a clear, smooth surface that feels soft against the skin while seated in your shield during pumping.

Why this insert matters

For mothers using larger shields, a smaller tunnel can help reduce rub and improve seal. The insert reduces the working tunnel from 24mm to 19mm, enabling a more tailored fit without replacing your shield.

• Reduces the nipple tunnel from 24mm to 19mm for a customized fit.
• Supports compatibility with Willow, Momcozy, Spectra, Medela, and other popular shields.
• Helpful for small-nippled individuals using larger shields.
• BPA-free, durable silicone that's smooth and comfortable.
• Maintains compatibility with most hands-free bras; insert fits inside the shield as you pump.

Who can benefit

Any pumping parent who notices discomfort with large shields or variable nipple diameter may find this insert helpful. If you measure nipple base circumference around 43.96–50.24mm and nipple diameter around 16–18mm, this insert can offer an improved fit during sessions.

How to use

• Place the insert inside your 24/25mm shield before attaching it to your Breast Pump Cup.
• Gently squeeze the shield so the insert sits evenly and seals without pinching.
• Use with compatible hands-free bra cups to preserve a streamlined pumping setup.

Care and safety

Clean with mild soap and warm water after use; the soft silicone remains clear and durable over time. This is a non-medical accessory intended to assist fit and comfort.
