DIY Air Down/Up Kit
Updated: Jan 18, 2020
These instructions will help you to build an air up air down kit that allows you to simultaneously air up or air down all four tires to the same pressure. It will also allow you to set the gauge to your desired pressure and walk away.
25’ Poly Hose (2)
Start with 1/4 air hoses. You will need 2 of these as seen in the picture below. Make the cut exactly half way on first hose (as shown in video). With the second hose, use just enough to make connections to your rear tires.
Notice the hose already has 2 male adapters. These will connect to your female brass tee.
The single side of the Tee will connect to the top of your air regulator. Each end of the pass-through will hook to each of the male adapters on the hose shown above.
Notice the thread compound on the male end already. This is the end that connects to your gauge inlet. Flow comes from tires. Follow flow arrow on gauge.
The gauge shown below will tie into above Tee on top. The below connector will be your female hose adapter (or male if you chose). This will hook into whatever compressor fitting you currently have.
