## Questions & Answers

**Q: Will these fit into Spectra 24mm flanges?**
A: I don’t own a Spectra so I can’t say for sure but they have fit the 24mm flanges on both my Medela and Tsrete Hands Free Pumps great without any issues. I’m not familiar with the Spectra but I think these would probably universally fit most 24mm flanges. These have been great quality flange inserts and I’ve been very happy with them.
