Hydraulic Tubing

Industrial Tube and Steel Corporation stocks the following grades of mild carbon hydraulic steel tubing.  

SAE J-524 Seamless

Covers cold drawn and annealed seamless low carbon steel pressure tubing intended for use as hydraulic lines and in other applications requiring tubing of a quality suitable for flaring and bending.

SAE J-525 Welded

Covers cold worked and annealed electric resistance welded single wall low carbon steel pressure tubing intended for use as hydraulic lines and in other applications requiring tubing of a quality suitable for flaring and bending.
