Blowguns and chucks are airtools used mainly by mechanics in auto shops. Blow Gun Kits include a sports ball needle, a raft inflater adapter and a Clip-On Blow Gun. The blow gun conveniently clips onto an air chuck, allowing you to keep an air hose dedicated to tire inflation. Blow guns are also used for clearing debris from a work space, drying wet surfaces and blowing up balloons. The best air chucks are made from a solid brass construction.
