Hello, This insulation is meant for 22mm pipe 15mm pipe would fit into this, but for a better fit you should ideally use pipe insulation specifically made for 15mm pipe. For the pipe insulation we sell the first figure is for the pipe size it fits, the second figure is for the thickness of the insulation and the third is the length of the insulation. This means that you need ECONOMY PIPE INSULATION 15 X 13MM X 1M (72357) for 15mm pipe. Thanks for using Q&A.
