how do i run air line through a wall

Hi all,

I want to run compressed air through a wall. I thought about getting 1/4 npt black pipe, put it through the wall and attach quick connect fittings, but then i realized if i did that, the pipe would be able to slide back and forth in the hole.

any ideas on how to stabilize the pipe or some better way to do this? see my amateur drawing attached

Thanks!

 

Spray foam should hold well and stop any drafts

 

Just make sure the ID is correct for the pipe

 

Use pipe about 3/4" longer than the thickness of the wall and thread fittings onto it

 

Exactly what I was thinking too...but now I like JustWood s idea better

 

Hmm, i kinda like that idea. I thought about getting a piece of pipe at the big box store, having them cut it to length and thread it so i could use the fittings to hold it in - problem is no stores around here carry 1/4". The lock collar looks promising! I have to order the pipe first on amazon and then double check the OD

 

Usually your local small hardware will carry black pipe and can cut it to any length you want

 

Why 1/4 inch?? run the pipe thru use 2 fittings one on each side and a fender washer behind the fittings to create surface area for strength or use the collars with fender washers behind them so when you push to connect it has some strength.

 

I was planning to put air lines all around the shop with drops at various locations until I came across an idea that caught my attention from Rock-n' H Woodshop.
He put his small compressor under a worktable, then ran short air lines up to a tool tray attached to quick connects. Anytime he needs to use an air tool, he can just hook up and go.
I'm trying to find the video

 

Found it.

 

I didn't think of this till you brought this up but I did my whole shop with a Rapidair Kit. They do sell the mountable blocks separate .
The kits are cheap and they have quite a few different configurations for different size shops.
I love how it turned out and it was fast to put together/set up.

 

I've been looking hard at the Rapidair kits (have it bookmarked), but not sure I need it just yet. Lowes sells their version as well for a better price.
I thought the quick connect setup might work for Dr.Faustus situation.

 

I would never point the air couplers up in a shop, imagine how must dust and dirt can accumulate in there.

 

Take a plate of a shape you like with mounting holes, put a hole to pass a proper size pipe coupling through and weld around coupling to the plate.

 

Good point, especially in a woodshop.

 

That will keep them from reproducing.........do not want a bunch of "little" couplers" running around the shop
