Flange Inserts 21/19/17/15mm for Momcozy S9/S12
Product description
These flange inserts are a set of transparent silicone adapters designed to improve fit and comfort when using 24mm breast shields with compatible breast pumps. They suit mothers seeking a gentler, more customised flange size without replacing whole shields, and they come in four sizes to help find the best seal during pumping.
Quick overview
This kit includes 8 silicone inserts in 21, 19, 17 and 15mm sizes that slip into standard 24mm shields. They are compatible with wearable and electric pumps such as Momcozy S12 Pro and S9 Pro, and with many 24mm shields from other common brands. The inserts are BPA free according to the manufacturer and are easy to attach, offering a softer contact surface that may reduce nipple irritation for some users.

Why it makes sense
A correct flange fit can influence comfort and milk flow, and these inserts give a low‑cost way to experiment with smaller sizes. They can help if you notice nipple swelling or discomfort with standard shields, but bear in mind that not every user will find a different insert more comfortable. The manufacturer recommends replacing inserts every 1 to 2 months to maintain hygiene and fit.
How to use it
Clean the inserts with warm soapy water and rinse thoroughly after each use, then dry before storing. For easier insertion and to reduce friction, a small amount of nipple‑safe balm or coconut oil may be used according to the product notes. Monitor nipple appearance during pumping and stop if you experience persistent pain.
What you get
The pack contains eight flange inserts across four sizes to try different fits. This makes it straightforward to test which diameter works best without buying multiple full shields.
