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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great replacement *by O***N on 29 May 2025* Perfect for my wearable breast pump, suction got better again ### ⭐⭐⭐⭐⭐ Great dupe *by A***R on 14 January 2025* I have been struggling to express much and didn't think about replacing the parts.
