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:
“All things are flowing, even those that seem immovable. The adamant is always passing into smoke. The plants imbibe the materials which they want from the air and the ground. They burn, that is, exhale and decompose their own bodies into the air and earth again. The animal burns, or undergoes the like perpetual consumption. The earth burns, the mountains burn and decompose, slower, but incessantly.”
—Ralph Waldo Emerson (1803–1882)
“There is a line between a definite maybe and an indefinite yes.”
—Mason Cooley (b. 1927)
