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:
“No jutty, frieze,
Buttress, nor coign of vantage, but this bird
Hath made his pendant bed and procreant cradle;
Where they most breed and haunt, I have observed
The air is delicate.”
—William Shakespeare (1564–1616)
“The middle years of parenthood are characterized by ambiguity. Our kids are no longer helpless, but neither are they independent. We are still active parents but we have more time now to concentrate on our personal needs. Our children’s world has expanded. It is not enclosed within a kind of magic dotted line drawn by us. Although we are still the most important adults in their lives, we are no longer the only significant adults.”
—Ruth Davidson Bell. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
