The really coarse steel wool works great for electrical ignitors. Its cheap, and easy to get. Although you can order NiChrome wire on the internet. But its damn expensive, like $10 for 100 feet, and that wire is freakin thin.

Anyway, heres a site that has very good directions for making electrical ignitors. I use steel wool, but make them like she makes the ones using copper.

yes you were being an idiot, but that dosn't answer the question. The answer is always use SCH 40 PVC on pnumatics. you CAN use ABS on combustions

You can use steel wool instead of NiChrome wire if you don't feel like scrapping a hair dryer.
And don't go egging their house...smear dog poo on their door knobs.

The propane meter has a special fitting on it that has a pin to push the valve down to open it. I have used them before, they are way way better than Bernz-O-Matic torch heads.
