PTC fittings and brass fittings for air suspension
ok, ive read all the complaints about PTC fittings, so just to be super safe im going with all brass fittings.
question is...how do these brass fittings connect to the airlines? i used to work on paintball guns and i totally understand how PTC fittings fit, cause cats had the option of going with steel braided or airline w/ptc.
so how do you connect the airlines to the brass fittings?!!? help please!

when you say brass, you mean compression fittings i'm assuming.
i kind of suck at explaining, but i'll try. ok, imagine the fitting, a brass sleeve and a brass nut... the brass nut will go on the airline followed by the sleeve. then, you put the airline into the appropriate hole in the fitting. the brass sleeve is now sandwiched between the fitting and the nut. tighten the nut, but do not overtighten it. then you are done. i'll see if i have a fitting lying around, then i'll do a pictoral.

not loctite that you put on bolts so they dont back out, but loctite thread sealant and it should be used on all threaded fittings (tank, valves, and bags). A quality PTC is just as capable as a quality compression fitting....

i don't really have any close up pics of my fittings, but if u want i could get a pic. Majicman described them well. Anyhow, i have a mixture of brass compression fittings, and ALL brass PTC fittings (the plastic ones suck i hear). I would find where a Parker Store is close to you and buy your stuff from them. They carry all DOT fittings, compression and PTC DOT brake line fittings rated up to 1000 PSI. I haven't had any problems with them so far.
I'm going to switch out my compression fittings for all brass DOT fittings when i add my front struts on i think, i don't like having them mixed and the PTC's are easier to use.
And definitely use some sort of thread sealant on all your fittings. I use some stuff called Rectorseal from Home Depot, works pretty damn good ... no leaks so far. You only need to use the sealant on threads, you don't need anything on the ends of your airline where they connect to either PTC fittings or Compression fittings. Also for comp. fittings, you don't need to put thread sealant on the threads that the nut goes on that crush's the sleeve around your airline. At least to my knowledge u don't need to

Quality plastic PTC's (smc and the like) are one of the easiest to use fittings. They actually have a higher crush rating then there brass counterparts. Any issue had with these is user error.
Cut line perfectly straight, Slide collar, insert line, slide collar, and pull the line outwards as hard as you can, line is now seated and just as reliable as any compression fitting.

water trap goes between the compressor and tank
