This useful tool features a normally-closed air chuck that can
be opened by pressing the lever on the inflation gun. Because
this air chuck is normally closed, the Tire Inflation Gun is a
perfect compliment to onboard air systems. To inflate a tire,
simply connect to an air line from your air tank and connect the
tire chuck to a tire or other inflatable item valve stem and
squeeze the tire gun trigger. This will open the air chuck and
release air from the tank into the tire. To check pressure,
release the trigger and note the pressure reading on the 0-200
PSI gauge. Carrying case included.  Tech Specs  6 lbs.
