I have a 2 meters long plastic tube with 8 mm inner diameter, and I need to pull 5 wires with a 6 mm diameter silicone tube through it. But all the different ways I tried were unsuccessful and It made me really frustrated.
What is the best way you propose for doing this?
I have limits in choosing a larger diameter plastic tube. As you can see in the picture, although being slightly tight, there is enough space for pulling them through the tube.
