@Wh4t3v3rs If you’re dead set on compressed air I would use this. And on the fittings use loctite liquid Teflon, good Parker brass dot fittings and air line. make sure the air line is cut nice and clean.
Others will probably have something different but that’s what works for me. I could see where it would be beneficial for “no trailer” races but I’ve never had problems with co2.
Btw, don’t put Teflon on the first two threads of the fitting.
