In this episode we're going to show you how to create a 4-way air management system that runs on any air compressor that has a quick disconnect fitting. We utilize this system to equalize tire pressure, deflate our tires for off-road, and inflate our tires when we're done wheeling.
I came across several adds on various social media outlets and decided it would be a good fit for us. After looking over costs involved, I realized I could save a ton of money if i just designed and built my own unit, with the added benefit of being able to repair it in the field.
Follow along and build your own for less.

I did my own 4 tire system one I did 3/8 flexzilla and one I did 1/4 flexzilla. The 1/4 was always faster to air up.
Bigger diameter hose wil take longer to fill the tires. You have to fill the extra volume of the hose before the tires will fill. The bigger hose may help will airing down but the bottle-neck is the shrader valves so I dought it will help. The cost of 3/8" compared to 1/4" is approx double. Also, the 3/8" system will take up room to store.
Exactly. He said a larger hose moves a larger volume of air. But if he used 6" diameter hose it's easy to see why that's not true, it would take more time to pressurize the bigger volume of hose, and the tires wouldn't inflate any faster because of the bottleneck of the tire valve. The 1/4" hose would result in a faster air up time.
I also made a 4 tire fill/deflate hose. One difference was a I bought a “manifold” from Menards.
Nicely done Seth 👍
Nice Set up!
I did a simular set up for my 3 axle Class A RV 20 years ago. Only a little different. I used a 120 volt air compressor and mounted a semi truck air tank to the inner frame. All my chucks ar permanently mounted in the wheel wells of the axles and I put air chicks at the front and rear bumper so I can use it on my 4X4. Much faster than the little ARB on my Rock Rig!
Like my Daddy used to say, "It only cost a little more to go first class, I just can't stay as long!"
Thats cool. I'm thinking about doing a version two with pneumatic hardlines run in the frame. I did get a tank mounted inline as of now.
That hose really bumped the price up, as well as upsizing all fittings.
On my own setup, which cost half what you paid, I used all my extra fittings to add air to garage at several places. My most favorite is a quick connect outside the garage on the wall, which I just plug in a pigtail line for quick work. Air connects on the bumper bars are next.
Adding a big ass heavy hose doesn't even help anything when using onboard air pushing maybe 6 cfm. A 1/4 inch lightweight hose would benefit you much more and would be more easily stowable. The determining factor for air hose size is CFM. You should build that thing with some 18 inch ABS pipe and see if you fill those tires up quicker.
Description updated with parts list
If I have a power tank could I essentially skip the ball joint and gauge and just use a quick connect at the first triple splitter since I have a gauge and trigger handle on my power tank kit? 🤔
Great video btw!
I would imagine so, assuming the power tank has a pressure regulator on it that'll keep you under 300 psi.
@@mulloutdoors yeah and I can check if I can trigger a deflate using the attachment too in the way the ball joint allows the airflow out, which I think it would. That’d take about $25ish off the parts cost I think. 🤙
Curious if you changed your valve stems to high flow? If not have you compared your times to that of the people that used 1/4” hose and fittings?
No changes made, this system works for me.
Thank you sir! I have a single ARB will it fill 35in tires? I heard it won’t
I don't have any experience with the single pump ARB compressors. I think the big difference between the single compressor units and the dual compressor units is the volume of air that can be moved.
Would the hose size matter I wonder since the schrader valve is so small? It seem that would be the dam in the system. Just curious. Nice diy.
Good point
I know I'd rather have less hose bulk to store than 2 minutes faster inflating as well.
That is another advantage to DIY you can customize your system to your needs/wants.
I run air-tools off of this and for me 3/8 gives me an advantage.
1/4" or 3/8" won't make a noticeable difference to four tires given the several 1/4" fittings the system has. But that said I appreciate the video. I know the work it takes to make them!
Can you post a link to or just add a parts list?
Sure thing, I will work on that as soon as I can.
Don’t waste your money on the 3/8” hose. 1/4” is plenty.
What compressor did you use on this setup?
I used ARB's twin compressor
Hey big dog. Can you get me a parts list? Appreciate the video. It looks a lot easier than I thought it would be
From another build: (not sure if it's all the same here)
Flexzilla 3/8" hose: (qty 1)
Flexzilla 3/8" hose ends: (qty 4)
Wynnsky air hose fittings:(qty 1)
Hex Manifold: (qty 1)
AstroAI closed system tire fittings: (qty 1 box of 4)
Barbed "Tee" fittings with hose clamps: (qty 1 box of 2 "tees")
Winters 60psi 3/8" center/back air gauge: (qty 1)
3/8" ball valve: (qty 1)
3/8" NPT elbow to mount the air gauge: (qty 1 pack of 2, but only 1 elbow is required)
If your using 3/8” hose and 1/4” fittings doesn’t that limit your flow to 1/4” as opposed to the intended 3/8 goal. Check out Apex design valves too for a standard tire 37s at 29 psi to 10 in 10 seconds left open.
Love my Apex rapid valvestems! Deflated my 35" Wildpeaks from 50psi to 15psi in 15 seconds per tire
