An air line is a tube, or hose, that contains and carries a compressed air supply. In industrial usage, this may be used to inflate car or bicycle tyres or power tools worked by compressed air, for breathing apparatus in hazardous environments and to operate many other pneumatic systems.[1]
Air lines provide compressed air for a wide range of uses and to cater for a variety of uses air lines are manufactured in a range of corrosion-resistant materials. Typically air lines are made with flexible hose or rigid pipe. Air line hoses provide flexibility and mobility for use, whereas a piped air line is more permanent and resistant to damage. For a typical compressed air system, both types of air lines are used in conjunction.
