Air compressors can be used to inflate tires, using a tire nozzle, in addition to countless other home tasks. The nozzle fits over the valve stems and forces air into the tire. The tire nozzle can easily be attached to the end of the air hose. If the air compressor is working properly but the tire is not filling with air, chances are there is something wrong with the tire nozzle and it will need to be changed.
Remove all pressurized air from the air compressor by opening the drain valve on the bottom of the tank. Turn off the air compressor and unplug it from the electrical source.
Unscrew the old tire nozzle from the end of the air hose. Place one adjustable wrench on the end of the air compressor hose and the other wrench on the tire nozzle. Turn the wrench on the tire nozzle counterclockwise while holding firm pressure on the other wrench. Remove the old Teflon tape from around the end of the hose.
Wrap a new strip of Teflon tape around the end of the air hose in a clockwise direction. The tape should be wrapped entirely around the tip two to three times.
Screw the new tire nozzle onto the tip of the air hose in a clockwise direction. Tighten the new tire nozzle down with your adjustable wrenches. Once again, place a wrench on the hose and another on the nozzle. Turn the wrench on the nozzle clockwise to tighten.
