It doesn’t make sense but 19mm was too big when it was the right size in spectra **Q: I used mine before realizing it’s the wrong flange size, should I still return them?** A: I did the same thing. I just brought flange inserts that were my nipple size and just pushed it in for the correct sizing. But you can if you want. **Q: Does this flange work with the Kiinde system?** A: Yes if you have the Kiinde adapters ## Customer Reviews ### ⭐⭐⭐⭐⭐ Interchangeable with other spectra parts👍 *by L***N on July 1, 2025* I ordered these because my swelling had gone down and I needed to drop down a size, from the 24mm to the 21mm and it was too soon for insurance to send a new one. These did not disappoint. Interchangeable with all my other spectra parts. Tubing, flanges, valves, all good quality, worked well, durable and functional. ### ⭐⭐⭐⭐⭐ Finally the Right Fit *by E***O on July 1, 2025* Thank goodness for these! Finding the right flange size made a huge difference in comfort and output. These 17mm flanges were the perfect fit for me. I just wish I had figured it out sooner. A must if you're not getting the results you want with the standard sizes. ### ⭐⭐⭐⭐⭐ Work great with Spectra S1 *by A***A on June 18, 2025* These work great with my Spectra S1, haven’t noticed any difference from the Spectra parts. As other reviewers noted, they work well with the Phillips Avent bottles too. They’ve held up well to constant washing and sterilizing/drying in a bottle sterilizer. Didn’t notice at first, but if you look inside the flange, it says the size --- ## 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.us/products/521414388-maymom-16mm-flange-and-duckbill-valve-compatible-with-spectra-s1](https://www.desertcart.us/products/521414388-maymom-16mm-flange-and-duckbill-valve-compatible-with-spectra-s1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-07*
