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 ### ⭐⭐⭐ Not very good quality. *by A***H on 26 May 2026* Flimsy with rough edges. ### ⭐⭐⭐⭐⭐ Best replacement parts for my Spectra S2 *by C***R on 29 August 2025* These replacement parts for my Spectra S2 were exactly what I needed!
