Then again, nobody said that it was actually safe 
to do so...  sure, if you wanna run the stuff 
underground or through concrete walls or the 
like, or it's in places where it won't be exposed 
to "adverse environmental conditions" or living 
things that would take exception to being 
perforated by shards of shattered tubing.


Somebody is likely sooner or later to come up 
with a material for plumbing air that behaves 
something like maybe Lexan or the like, which 
simply refuses to shatter or splinter, which may 
well make good air line material (to a point) but 
to date it's not happened just yet, at least nothing I know of.


If I ran lines like this, they'd be soldered 
copper, cheap enough and easy to work with and 
once it's there it's there and done.    Might do 
it yet, currently  still simply dragging hoses around.
