1/2 NPS SCH 40, (0.840" OD, 0.109" W), 6061-T6 Aluminum Pipe

NPS stands for Nominal Pipe Size. It's a dimensionless number used in North America to indicate the size of pipes, valves, and other related components in a piping system. It's not a direct measurement of the pipe's actual dimensions, but rather a convenient way to refer to a specific pipe size.
Please refer to OD, ID and Wall for actual size of pipe.
Extruded Structural Aluminum Pipe. 6061 aluminum alloy is a general purpose alloy with excellent joining characteristics, good acceptance of applied coatings. 6061 combines relatively high strength, good workability, and high resistance to corrosion; widely available in most shapes.
