INSTALLING THE TIRE INFLATION KIT

Getting Started

The Tire Inflation Kit comes with a 30-foot coil hose, a tire inflation gun, a mount for your air chuck, and a small kit to add an air chuck to your vehicle (air source relocation kit).

Plumbing

Let's start with the Air Source Relocation kit. This kit comes with a 15' section of 1/4" air line, two 1/4" brass compression fittings, and a quick disconnect stud with chuck. The stud can be set aside for now. Let's focus on the two brass fittings and air chuck that come with this kit.

You will need to plumb one of these brass fittings into our air tank. These are designed to fit in a 1/4" NPT port. Start by plumbing one of these fittings into a 1/4" port on your tank*. Once complete, we can then start looking for a good spot to mount our air chuck.

*5-Gallon tanks and larger will require a 1/2" NPT x 1/4" FNPT Reducer to use this kit.

Mounting the air chuck

The air chuck can be mounted in any location that is convenient for you. We typically see the chuck mounted on the rear bumper of the vehicle when installed, for easy access. Once you have decided on a mounting location for the air chuck, we can assemble our mounting bracket for the chuck.

Position your air chuck on the outer portion of the bracket, and thread the brass fitting into the chuck from the inside of the bracket. It should look like the image to the left when completed. You can use a wrench to tighten the fitting into the chuck until it sits tight with the bracket.

Now that your air chuck and bracket are prepared, we can use the two supplied screws to secure the bracket for the vehicle. You can use a drill with a Phillips-style bit to finish installing your mounting screws for the bracket.

Getting Air to the Chuck

This last step is the easiest one to complete. Now that our air chuck is in place, we need to plumb air out to it. We can use the supplied 1/4" air line to run air from the tank out to the chuck.

Start by removing the nut from the compression fitting. Take your 1/4" line, and insert the line through the center of the nut, with the threads facing towards the end of your air line. (see image below) You can then seat the airline over the barb on the fitting. It will take some force to get this in place.

It should look similar to this once you have completed the steps above. At this point, slide the nut down to the brass fitting and tighten it up over the line. It will be a bit hard to tighten, and a wrench can be used to fully torque this fitting down. Make absolutely sure the line is all the way over the barb, as it will leak if not seated fully.

To finish your install, you can repeat this process for the compression fitting on the air chuck. Once tightened up, start your vehicle and allow the tank to fill up. Check each fitting for leaks and adjust as needed.

Finishing Up

Now that the hard part is done, let's take our coil hose and plumb it into the chuck. You can insert the coil hose into the chuck by pulling the collar back on the chuck, and pressing the 1/4" quick connect stud into place. Release the collar on the air chuck to secure the hose in place. Finally, insert your tire inflation gun into the female end of the coil hose, and start filling up your tires.
