Non resistive spark plug wire works well, too.
You could use some silicone or rubber test lead wire, which is inexpensive and can be found most anywhere, or, you could use the center conductor and insulation of some RG-59 you have around the shack, which is good for 3KV.
I've used it several times for amplifier HV plate supplie leads. I use the wire with the solid inner conductior insulation.
It's a funny coincidence, you suggested that. The wire I ordered came in last night, so I wired everything in the amp up with the new high voltage/ high $$$ teflon, then straightened the bench out for the night. I went to put the left over new wire away in the "Teflon coax and special cables" drawer --- And saw some old multimeter test leads with 'oddball connectors' on the tip ends. I had a good laugh and promptly kicked my own booty! Great suggestion though. This old meter lead wire is rated 3KV (the one that's clearly-marked anyway).
