Home made tank Drier

[ChrisDee]

Home made tank drier. Issue is copper / brass can scrape into tank threads / create a stress crack on inside / bottom surface. According to Faber, Asahi,...this is a serious issue. And is stricktly forbidden. DOT / NHTSB also warn of this. Same issue back when that company made SS tanks and they came into contact with multiiple iron fittings, etc. The mere touch of iron on the tank left a area of corrosion that hard buffing couldn't remove and the tanks evertually failed in the affected area.

Yeah, I just use pvc. Have one stand made from old table saw frame (wheels on bottom). I can run a water pipe up to flush, then swap out for hot air pipe in a few seconds. For O2 Clean, the air pipe is from existing clean scuba tank.
