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 ### ⭐⭐⭐⭐⭐ Review *by L***8 on 2 April 2024* First and foremost, I must commend you on the exceptional quality and functionality of both the silicone duckbill valves and diaphragms.
