4 tire inflator/deflator

With my ARB Twinair, I can fill a 33in tire from about 30 to 60 in just a couple minutes.

Good idea. I thought about it but opted not to because I fill the fronts and rears to different pressures.

Adjusting the pressure is as easy as turning the knob between fronts and rears. The gauge reads exactly what pressure your filling the tires to. So, fill them all to the low setting, remove two hoses, turn the knob to the new pressure and your done. I really like your air chucks too, I only have one that clips on, but without a check valve, so I have to unplug the compressor hose, then the end on the tire to avoid loosing air.

Nice project. If you air down for dirt regularly, you should have the ExtremeAir Frame mount compressor.

Good to know, I'll have to look into the regulator more.
The air chucks are awesome. I could never get the other types to work well. I have to say I originally balked at the price, but they've been worth every penny.

Neat. With all that work you should up your hose clamp game. Get the ones made for fuel lines that don't bite in to the hose.

Or get the one-and-done type and a Pex crimper. You should buy a pex crimper anyway. Everyone needs one, especially SMB owners.

Great post! I just picked up a single ARB compressor myself and was in the process of sourcing deflators and an inflator with gauge. Seems your set-up (along with a few of the fellow member's ideas) would meet my needs very well. This is a great forum!

Excellent points 86Scotty......but allow me to be a bit anal for a short while.

The single and double ear clamps you link to from McMaster-Carr aren't used for PEX tubing as the clamping techniques are different. I've used those in your link to great success especially in tight spaces were the screw-fastener types are too bulky. I like the pinch clamps as they're not prone to loosening should the clamping screw somehow work itself loose. While that's an unlikely event it has been known to happen.

Of course those clamps are not reusable but they're so inexpensive that's not a problem. Having had to replace them after making up an assembly they're easy to cut and remove with the proper type pincers. I prefer these as they allow various tool orientation during both installation and removal: https://www.amazon.com/Knipex-Tools-...HVJ3PP92RFJV00 (Fantastic high-quality tool, cheaper than McMaster.

The linked clamps are great for automotive and usual air-deliver hose formulations. Just be careful to accurately assure the unmade ID as that greatly affects the final clamping action and long-term holding power under a load and temperature.

Thanks for your indulgence!

Having some type of inflation system really reduces the wear and tear on the knees. Using a regulator set up also reduces the need to keep checking the pressure as you reinflate. Hook up the hose and wait for the compressor to stop running, boom, your done. With the four hose set-up, you could easily deflate all the tires at once. With my single hose setup, I still use an ARB deflater that pulls the valve core out. It deflates the tire in seconds, but must be moved to each tire individually where as the four hose system would allow deflating all at once, but since the valve stem is still in place, it will take longer. Either way, it's far better than having to hold the air chuck on each tire and continually having to check the pressure.

I wish I'd seen those clamps from Summit Racing, looks like a much better system than the worm-screw variety. Of course, it would have increased the cost of the system substantially

I'm going to look into the regulator, that might make the whole system even easier! By the 3rd or 4th iteration, this'll be the Taj Mahal of inflation systems.

Nearly everything I'd done or concocted on my van builds has gone this same way---each time out more of a prototype than a finished project. Its not always fun but in the end we end up with great creations, one where the next guy will think its easy.
