An air line is a tube that carries a compressed air supply, e.g. to inflate tyres or power compressed-air tools. Air line is most commonly used for suppling compressed air to air tools in workshops and in air brake systems on larger vehicles. The most common sizes of air tubing are one quarter inch and three eights inch outside diameter tubing although a complete range of tubing in both standard and metric sizes is available. Air lines are also used for diving where s compressor or a hand-powered air pump supplies air to a diver.
Famous quotes containing the words air and/or line:
“The air was clear. He seemed in ultimate peace
Except that he had no eyes. Rigid and bright
Upon the forehead, furred
With a light frost, crouched an outrageous bird.”
