BiMetallic gauge repair

Does anyone have a supplier for the fiberglass insulated nichrome wire?

Looked on Amazon and did not see anything


I suppose one could get very fine fiberglass and pull out fibers coat the nichrome in lacquer and roll the nichrome in the fibers.

I bet the nichrome in my now DOA IVR wore through the insulation at one of the bi-metal edges made contact and melted or wire through. ( Nichrome was broken in one of the wraps at the edge of the bi-metal)
