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:
“My companion and I, having a minute’s discussion on some point of ancient history, were amused by the attitude which the Indian, who could not tell what we were talking about, assumed. He constituted himself umpire, and, judging by our air and gesture, he very seriously remarked from time to time, “you beat,” or “he beat.””
—Henry David Thoreau (1817–1862)
“Writing fiction has developed in me an abiding respect for the unknown in a human lifetime and a sense of where to look for the threads, how to follow, how to connect, find in the thick of the tangle what clear line persists. The strands are all there: to the memory nothing is ever really lost.”
—Eudora Welty (b. 1909)
