Welded Hydraulic Tubing (SAE J-525)

Welded Hydraulic Tubing (SAE J-525) 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.  Used for pressure lines in applications requiring high-quality tubing for bending, flaring, forming, and brazing.

Made from 1006 to 1018 Steel
Meets SAE J-525
J525 Welded Hydraulic Tubing Tolerances

Stocked Size Range:

  • 0.250” to 2.000” O.D. from 0.028” to 0.120” Wall Thickness
  • Stocked in 20.000’ lengths (cut to length available)

Manufacturing Process

Welded hydraulic tubing is made from flat-rolled steel shaped into a tubular form where the edges are joined and fused together by electric-resistance welding.  After forming and welding, the tubing is then normalized and subjected to a cold-drawing operation.  Following cold working, the tubing is then normalized via an atmospherically controlled method to produce a finished product that will meet requirement of SAE J525.

Benefits of Welded Hydraulic Tubing:


  • Exceptionally Bright and Clean OD and ID.


  • Designed to withstand fluid pressures due to being highly tested and cold worked.


  • Quality and chemistry are carefully restricted.


  • Very good for bending, flaring, forming, and brazing.

Applications by Industry

Welded Hydraulic tubing is used in any application from aerospace to heavy equipment in which fluid transfer is needed and/or where bending and flaring are critical.
