TP160 Polyamide "Nylon 11" Tubing, Inch OD, 0.04 Inch Wall Thickness, Up To 250.00 PSI

Flexible nylon tubing like this gets used across a pretty wide range of applications. Low-pressure hydraulics, air lines, lubrication systems, instrumentation, and gas, chemical, and oil processing are all within scope. The Nylon 11 construction handles liquid and gas transfer well, and with a working pressure rated up to 250 PSI and a temperature range of -40°F to +200°F, it holds up in most shop and field environments without much fuss.

This TP160 polyamide tubing is designed for use with both liquids and gasses, so it should work well for air lines. It's also pretty tough stuff, made to resist abrasion.

For size, the tube outer diameter is 0.3125 inch, which is 5/16 inch OD, with a 0.04 inch wall. On pressure, it is rated up to 250 PSI maximum working pressure.
