As i think 25mm is the shrunk round diameter.** A: If you use pie, calculate the circumference, and divide by 2 that would get the size you are asking, personally, I don't see the point, you have plenty of flexibility to heat shrink items you require just order big it will shrink down **Q: Hi. Is it 25mm flat or diameter?** A: All the heat shrink I bought came flat at 40mm, when I tried I was able to push a 25mm holesaw through it. So yes it is 25mm diameter. Note, this stuff is very stiff when you shrink it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect *by A***R on Reviewed in the United Kingdom on 17 February 2024* Works perfect and easy to use ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Very surprised how well it did! *by L***S on Reviewed in the United Kingdom on 13 July 2022* I was a bit sceptical about it at first but got surprised how much it can actually shrink!I had to fix shower hose and even messed up the way I did it. It was easy enough to remove and install again the way I wanted. In addition the glue is providing very good seal.After w month of daily use, it's doesn't show any wear.It is much stiffer than typical cable shrink tube but I would say this is for a different purpose. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Works well. *by T***T on Reviewed in the United Kingdom on 15 July 2022* Does what you’d expect this to do.
