I grew tired of my OBA hoses failing every other trail ride because of the high heat and the age of the hoses (and even the replaced hoses kept popping off).
I had been using a barb-style fitting on the compressor output, but finally ponied up for this 1/2" NPT fitting from Kilby.
I reworked the piping to use metal pipe as much as possible, and as close to the compressor as possible, to give the compressed air a chance to cool down before hitting the hoses.
The drop going to the rear of the Scout goes to the old 3-way "T" (pressure relief valve, gauge, and quick connect) and to the pressure switch.
The drop doing down at the front of the Scout goes to a quick disconnect, which goes to a hose leading into the front bumper air tank.
The quick disconnect is in case the bumper is damaged and won't hold air, I can disconnect the bumper from the system, and go back to using my OBA like I used to, without an air tank.
