Back in October of 2014, I ordered a couple of air chucks to experiment with so that I could make up a 4 wheel tire inflator/deflator. The air chucks had been sitting in the top drawer of my toolbox until now. I got busy on the project once again and finally up the 4 tire deflator/inflator.
These are the stay-on air chucks that I ordered. The one on the left with the lever is quite nice but it is just not as secure as the one on the right. The one with the lever has just a single clip and the one with the pull back collar has two clips and fits more securely. The one on the right also pushes onto the valve stem easily and you donít need to pull the collar back to do this.
So fast forward from 2014 to earlier this week (May 2018) when I ordered the rest of the parts. I had been planning all along to use quality components. While you can order one long hose and cut it to fit using fittings and hose clamps for less money, I wanted a more ďfinishedĒ quality to finished product so I ordered pre-made Goodyear hoses with a 10 year warranty. I also used a digital tire pressure gauge with backlight and rugged outer case. Rather than using the blocky brass fittings, I found smaller, more rounded fittings.
The Goodyear hoses are available in yellow, red or black. I picked yellow so that they are as visible as possible on the trail.
Everything coils up nicely and is just a little bit larger than a single 50 ft. air hose that you would be carrying anyway.
The lengths work perfectly and all hoses are equal length.
For my driveway beta test, I took the tire pressure down to 7 or so PSI just like I do on the trail. Air down was damn quick but I did not time this first try. Seems like it took about the same amount of time as it usually takes to deflate 1 to 1-1/2 tires. The pressure gauge will go to zero while you are deflating even though you are not at zero yet. Once you hit zero, close the valve off every so often to check where you are. I took it down to 7.5psi today at all for corners.
Air up took about 18 minutes using the ARB twin pump under the passenger seat. This was for airing up 4 37Ē tires from 7psi to 32psi Ė just like I do at the end of the trail. FWIW, this test was done at my house which is barely above sea level. With the TPMS system on my Rubicon, I was able to watch all four tires inflate real-time. Pretty cool.
The pressure gauge reads about 1psi higher than the actual tire pressure while you are pumping up. Shut the valve to see the correct pressure.
