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.

“More beautiful and soft than any moth
With burring furred antennae feeling its huge path
Through dusk, the air liner with shut-off engines
Glides over suburbs”

Wheel and go,leaving air in shreds
black beaks shine in gray haze.
Brushed by the hawk’s wing
of vision.”

All Americans must be prepared to make, on a 24 hour schedule, every war weapon possible and the war factory line will use men and materials which will bring, the war effort to every man, woman, and child in America. All one hundred thirty million of us will be needed to answer the sunrise stealth of the Sabbath Day Assassins.”
