ARB Tire Inflator (do it yourself)

Airing down is a HUGE advantage while on the trail. It gives you a wider foot print. What do you do if you go out and nobody has a compressor? You don't air down or you leave the trail head with 4 low tires.

After my ARB install it was obvious the air compressor was powerful enough to run the air lockers with a flip of a few switches. It dawned on me there was a kit available to turn the ARB compressor into a tire inflator. Looking around on the net I noticed the price of a inflator kit ranged from 30-50 dollars depending on where you looked. I was simply amazed that the contents of the kit was an air hose and a few fittings that plugged into the ARB compressor. Toying around the garage I decided I could probably build one for alot less and do exactly what the kit would do.

All the pieces I used in this kit where store bought at my local Home Depot. I had a 3-inch piece of 1/4 brass tubing and a 1/4 quick disconnect fitting from my existing home air compressor setup. My ARB compressor was installed on the Aux. tray on the drivers side just under the brake assembly.

Did I do any testing?
I took a 33x12.50 tire and deflated it down to 12psi my normal offroad pressure. My goal was to see how it would take to fill it backup to 28psi, which is my normal street pressure. Personally I think the numbers are pretty good. ARB says the compressor can run for 45minutes and then needs to cool down. A tire here and there is a lot less than 45minutes especially for a backup tire inflator.

Time PSI
0-2 minutes 12 to 21psi
2-4 minutes 21 to 29psi

I purchased a 1/4 "T", a 1/4 male to male adapter and the 3-inch 1/4 inch brass section I currently had laying around in the garage.

Look at the back of the compressor. See where the red and blue wires are in the back of the compressor tank.

Remove the blue and red wires from the pressure switch.

Turn and remove the pressure switch from the back of the ARB air tank.

Notice the backside has a hole in it now. That's where we are going to tie into.

Use some plumber's tape aka Teflon tape and wrap every piece with threads a few times.

Starting from the tape air will leave and enter the 3-inch tube - male to male adapter - T - to the pressure switch and the quick disconnect.

Assemble the 3-inch section of pipe, male to male adapter and the T.

On the bottom of the base there is a 10MM nut that you can adjust to shift the compressor side to side and in this case you can tip the compressor over towards the fender to make it easier to install the fittings.

Screw in the pre-assembled section including the T.

Thread the pressure switch onto the bottom of the T. Notice how a hand will fit barely under everything on the right.

Also a hand will fit under the left side.

Thread in your quick disconnect coupler.

Reconnect the blue and red wires to the back of the pressure switch.

Turn on the air and pray for no leaks. If there is a leak. Check all your connections and make sure they are snug, but not over tight.
