Gigamanx, I think I have the same question.

Getting ready to plumb my airbag system and would like to hear experiences with either hard or soft line too.

DOT approved push-in fittings are kinda expensive and I hear a lot of guys complain about chasing down leaks.

My plan is to plumb the airbags in -4 AN fittings (1/4" tube) with aluminum line. Stainless might be a better option, but it is difficult to flare without cracking and the fatigue resistance of the aluminum should be ok if it is fastened to the chassis correctly. To keep the cost of down for the AN fittings, I'm using steel JIC fittings, nuts and sleeves.

I have a Parker Rolo-flair tool to make the flares in the aluminum and have had good luck making leak free connections with it. For the threaded connections, the plan is to use a anaerobic thread seal (Locktite 565) instead of teflon tape or pipe dope.

Any other suggestions from guys with bagged trucks?
