Your best and cheapest solution may be to use a VTN-200 heat shrink to
cover your standard PVC sheathed multicore. VTN-200 shrink is chemical
and oil resistant and easily available. eg. Ebay # 251726064642 Might be
an idea NOT to shrink it as it is more flexible unshrunk.

That’s a great idea. I’ll check it out.

Thanks.

Shrinking the right size choice can be flexible, but also then becomes
THICKER, as in a better armor against abrasion.
