I have researched this online but have not found a clear answer. It seems that when people mention running air lines in the attic, debates quickly start up about copper vs black pipe (then someone mentions PVC and everybody else moans and says “here we go again”)

I’d like to run an air line from my garage to another room of the house, through the attic. Less than 50’.

Usage: light duty. Infrequent. Mainly to be able to use the blow gun around the house.

For $29, I can buy a 3/8” Flexzilla 50’ and be done. I would make connector boxes at the ceilings so no hose needs to go through the walls. Attic is typical Missouri attic with cold winters and hot summers.

May I simply run the hose, or do I need to do anything fancier?

Id give it a go. You can always install a shut off in the garage in case it would blow

OK, let me be the contrarian. If this is going to be constantly under pressure, i.e. not only charged when needed, I would not go with a non-metallic supply line. Why? Because, the heat of the attic will eventually degrade the plastic, rubber whatever and if it blows when you are not there the compressor will run an run and run and overheat and possibly cause a fire. The chance is small but is it worth it?? Not in my house. I always run 1/2” galvanised pipe, not that expensive but as my dad always says – “Cheap is expensive”. Good luck.

In addition to cut-off valve, perhaps an easy way to bleed pressure off when not in use.

I make a practice of making sure my air compressor is shut off/ unplugged whenever I’ll be gone. That way if an air connection did go, the machine won’t run and be a hazard, or simply waste electricity / put extra wear on it. I agree with the rest. Run a flexzilla hose. They are good stuff.

I have my compressor connected to my shop from a separate building and have just a hose for it. Been there four years now and still working fine. I keep the pressure at 90 lbs.
