Air line

An air line is a tube, or hose, that carries a compressed air supply. In industry this may be used to inflate tyres or power compressed-air tools or other pneumatic systems, or for breathing apparatus in hazardous environments. Air line is also used for supplying compressed air in road vehicle air brake or railway air brake systems on larger vehicles or rail cars, and air lines are used in underwater diving where a compressor or a hand-powered air pump supplies air to a diver for breathing or other uses.
