Review: True to Size for Manual or Electric Breast Pumps - Flange inserts that are your size are key in successful, comfortable pumping sessions. As always, do your research to find your correct size. The 19mm size was what I needed and they are a sturdy silicone type material that fit just right in the flange. They do not slip, they did not cause any loss in suction. They worked just as intended. Over many washes, these inserts did not warp or tear in any way.
Review: 19 mm insert - Fit inside larger flange and gets the job done. Soft silicone material so not painful rubbing or discomfort

## Questions & Answers

**Q: Will these work with elvie?**
A: Can you tell me how to cut them? At the end or beginning? It’s not sucking properly

**Q: Will this work with the spectra hands free cups?**
A: They did not work with my spectra Cara cups. Had to buy the long inserts instead.

**Q: Will this fit in momcozy hands free breast pump?**
A: It does, but it’s not as tight of a fit as some other brands.

**Q: How can I keep these inserts from backing out of my medela 24mm flanges?**
A: You should be able to push it in enough where it won’t pop out, if that keeps persisting I’d return and get new ones. Mine fit in perfectly.

Fit inside larger flange and gets the job done. Soft silicone material so not painful rubbing or discomfort

### ⭐⭐⭐⭐⭐ Does the job
*by C***. on February 15, 2026*

Works. It fits into 24mm flange parts, fits comfortably for me. The only thing I'd say is that it makes the window where the milk comes out harder to see bc its more opaque, but it does the job.
