I did some research on the web, but there isn't a clear answer on this. I found some forum posts but still not sure. Looking to colour my hydraulic brake hoses cables of my Saints M820 brakes.
I found out that the brake hoses are 5mm in outer diameter. So I am looking around for electrical heat shrink wrap that goes over my brake hoses and then shrink it.
So for the electrical heat shrink - the shrunk diameter should be 5mm? (Because the electrical heat shrink comes with a normal diameter, and the shrunk diameter. The shrunk diameter is after you used the heating gun. Not sure if it's OK for the hoses to have like a 4mm shrunk diameter over it.
