It's 15mm connector and should connect 15mm copper pipe. **Q: Hi, does anyone if you can use these to connect 2 flexi pipes together using the nuts already on the the flexi pipe?** A: Yes, I am using them for exactly that but you will need the metal sleeves to go inside the plastic pipes to stop them collapsing. **Q: Does this come with olives?** A: Yes it has olives inside, it's what makes the seal. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked first time: no leaks. *by S***R on 17 May 2021* With so many of these parts being manufactured in China these days, it's commonplace to experience poor engineering and therefore leakage.
