I want to send a 95/5 percent mix of 02 and propane down a tube underground
into gopher burrows. I will have a piezo sparker at the end of the tube
back a bit so it doesn't get plugged up with dirt. Perhaps inside a phallus
shaped protective head with many drilled holes. I'm thinking of something
flexible for the hose. Inside that, I have to run the two wires to the
piezo. I might be able to run one, and use the hose as a ground if it is
made of metal, like a smog sensor hose. Piezos on barbecues have one wire.
My question is: Is there wire that has coatings that are resistant to high
temperatures? I know there are lots of such wires in stoves, but most I
have seen look ratty from use. There would be a flash and explosion, but no
terribly high temperatures for a very long period of time, as all the oxygen
would be consumed in the explosion.
What would such wire be called, and where do I get some?
Thanks. My Gopher Getter is moving along now that I'm getting some of these
other projects out of the pipeline. I hope to be ready by gopher time in
spring.

Try teflon coated wire. It should last a long time in this
situation. The peak temp will be much higher than the wire rating,
but it probably won't last long enough to damage the wire. Here is
one source: http://www.weicowire.com/wirecablecontents.htm
PS...better have a good flame arrestor/backflow preventer on the
supply tube to prevent a major backfire in the tube, regulator, tanks
etc. Propane/O2 burns with a nasty bang.
