i have run out of thing to build for my truck. so i've always wanted on board air. but without a compresser for now.

i went and got some 5 1/2" pipe for a metal shop for free. i cut it and have welded on some end caps to the pipe. now i need a way to get air into the pipe. i was looking at tubless nipples for tires. bgut they are only good up to 60 psi. i fugure my tank will be able to take up to 200 psi and hold a lot of air. i need something to just hook a tire chuck up too and fill my tank at any gas station. any ideas. i found plenty of things to get the air out.:confused:

anyone know where to get pneumatic fittings?

i looked at grainger.com, but couldn't find anything i was looking for!:confused:

thanks:smokin: :D

I just went and bought an 11gal tank from the local parts store. Cost me $50. But if you're dead set on building it then go look at a manufactured air tank and the hardware they use.

Hmmm, I built a portable tank. I got a valve from the local hardware store. All brass, screws into a standard 3/8 NPT, looks like a tire valve, don't remember what it's called. Screwed that into an 3/8 NPT “T”, along with a quick connect, with a ball valve between the T and the tank just to make sure no leaks from the valves.

I am planning on making a spare storage tank for my tini little garage compressor to act as excess storage to run air tools out of an old propane tank. has anyone done this before and could I also rig this up for somewhere on my rig using a converted AC condensor to fill the thing?

i went over to big r they hadome stuff, but i could'nt find the filling thingy. maybe i'll go check out tractor supply company tonight.

i checked harborfreight too, a lot of cool things but no :smokin:

only good for 60 psi?? the lt tires on my dodge hold 80psi, I'm sure you can get a tire fitting for more.

I read somewhere about a guy using an old fire extinguisher as an air tank. Just swaped out the valves on top.

Just put airline fittings on it the same type as your air tools or air hose. It you want you can throw in a T or air gauge to let you know what pressure you have or if you have any leaks.

That's what I built my little portable tank out of. I had an old Propane tank that leaked, and the fitting on it didn't fit anything I have. So, one trip to the hardware store, about $20 in fittings (Adapter bushing in the tank, "T", ball valve, air chuck valve (whatever they are called), quick connect coupler, 10' of air hose) and screw it all together with Teflon tape. Works great. Even has a 1/8" steel wall around the valve/T assembly so it can roll around and smack into things without ever hitting the fittings.

Ross, go to a truck tire center and buy some truck tire clamp in valves. Then all you have to do is bolt them in. Just make sure you bolt them in before you Weld shut the air tank.

They hold truck tire pressure over 140psi cold. + 4% raise when hot.

If you are airing up at a gas station you are only getting 95psi anyhow. Air tools work best at 85-90 psi. And most gas stations have regulators to keep it under that.

My airtanks are my bumpers Just used npt fittings and use a rotory A/C compressor. All you do is WD40 that puppy when you use it. :D Air pressure to 125psi all day long. Yes it gets hot.

For those interested in changing a propane tank over...I just came from OSH store and in the tool corral I saw a complete change over kit for $24...There are tons of those tanks that you can get for free or cheap at a garage sales....:D

What are you worried about ....gas stations don't have 200 psi....:confused:

How thick is the metal you used? What did you use to weld it all together? I'm just curious as to how you figure it will hold 200PSI.

most compressors shut off arounf 120 psi. If you want volume , get scuba tank. $2 to refill, 80 cubic feet at 150psi delivery pressure. Not quite the volume of co2, but 1/6 the price.

The cheapest way is to just use steel NPT plumbing fittings, you can weld them onto your fabbed Pipe tank. You can use 1/4" air hose and clamps on barbed fittings, you can hard pipe it, or you can use quick connect coupleings.
Thats the way I ran my 1st system off of my York(very bulky, and hard to repair leaks if/when they occure).
I can tell you from experience though, that the best and easiest way to plumb your air system is to go to an industrial truck supply or a Kenworth Dealer(or a nation wide hose supplier like House of Hose), and get the DOT approved quick connect air line and fittings. You will be able to fit your system into an area 1/3 the size of a hard piped system, and it installs in an hour, (also repairs easily).
Here is my current air system, compact,easy to access, and holds air with almost no loss(wont leak down from 150 psi to 135 psi over the course of a weekend).

natural gas pipe line! good up to 500 psi!:D

i used a flux cored 220 welder with argon! it isn't coming apart!:flipoff2: i figure it'll hold 250 easy.

Whats OSH? Anyone know of any other chain stores that might carry something like this?

i found a 5.5 gal lpg tank at a flea market. put on some fittings and mounted it to the bottom o my tun just infrom of the gass tank. works great.

it was a cylindrical tank and not one of the big round ones like used on gas grills.
