Review: These worked perfectly with my Spectra. It was nice to find these flanges at such a good price that also worked with the pump I was using.
Review: These fit pretty well. No leaking and built great. Love supporting small biz too. For any flange I’d recommend keeping it at a slight angle lower so milk flows right down.

## Questions & Answers

**Q: Is there 2 per order?**
A: Yes. 2 pcs are included.

**Q: Can you use standard spectra duck valves on the flanges? Or do you have to buy this brand to replace**
A: Yes but i returned these and bought maymom. The designed its flawed leaving milk to leak if you tilt while pumping in anyway this is because the bottle doesnt screw in all the way it leaves a space which is senseless because sometimes mothers have to squeeze and pump at the same time which makes us tilt the bottle by accident.

**Q: Can this be used sign the Ameda Mya pump?**
A: I’m unfamiliar with that pump. I did buy an adapter to fit these on the medela bottles.

**Q: Do these fit MAM bottles?**
A: No. But they will fit Phillips Avent bottles.

### ⭐⭐⭐⭐⭐ Review
*by A***O on 24 June 2024*

I was in need of a second set of flanges as I am exclusively pumping and didn’t want to constantly clean pump parts. I found these after a quick search and they’re perfect! I haven’t had any issues. They fit perfectly on my Spectra pump. The valves can be a little difficult to remove but a little twist at the base does the trick. Will purchase again when I’m in need of replacement parts!
