Much more comfortable than using the machine's ill-fitting size 24 stock flange.

I recommend getting a spray bottle of water and spraying inside the flange before trying to put these in so that they slide in and out a little easier. It’s also a lot easier to clean water than to use nipple cream. ## Frequently Bought Together - Flange Inserts 17mm 8PC Compatible with Momcozy S12 pro/S9 pro/S9/S10/S12/Medela/TSRETE/Spectra/Bellababy etc 24mm Wearable Breast Pump, Reduce 24mm Tunnel Down to Correct Size - Medela Manual breast pump with Flex Shields Harmony Single Hand for More Comfort and Expressing More Milk --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/587800604-flange-insert-3pc-17mm-for-momcozy-s12-pro-s9-pro](https://www.desertcart.hr/products/587800604-flange-insert-3pc-17mm-for-momcozy-s12-pro-s9-pro) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-29*
