So we are creating a hallway with all kinds of creepy crawlies for a new side haunt. I had an idea of using several air lines on both sides of the hallway to bombard the guests with tiny blasts of air - I could have sworn i saw a setup like this somewhere else but now I can't find it.

I am looking for a way to attach the 1/4 inch tubing to holes in the wall - My first thought were small push on flange style fitting, but they don't seem to exist - My next idea was to use standard threaded push on male fittings, the kind that screw into pneumatic cylinders, push the thread through the wall from the back then screw a nut on the front side of the wall to secure it....down side it I would need to find 10mm "Extra Fine Thread" nuts, which I can order but wanted to see if anyone else had any ideas that may work better for this idea.
