The kind I used had its own heat resistant insulation. I think it was a woven fiberglass type of material. It was something like this:https://www.ebay.com/itm/Electric-H...377799&hash=item343072d74f:g:ApIAAOSwFD5fWS0I
I just used a length that was 4 times the length of the flex conduit and folded it in half twice before pulling it thru.
What did you use for a power supply to heat the Nichrome Wire?
