In a different forum a user made insulated stainless zip ties .... They said ....
"I decided on a stainless zip tie. But to keep the sharp edge of the stainless from cutting into the hoses over time I used industrial grade PVC heat shrink. That stuff is really tough."
There's a picture of the insulated zip tie on the Lincoln forum but it's a docx file and I can't attach it here.
If you want to see the picture, go to https://www.thelincolnforum.net/phpbb3/ ... 68#p409168
