Hydraulic Pressure Line Tubing Data

Team Tube Ltd., stocks Hydraulic Pressure Line Tubing in both seamless and welded grades, with both grades designed to meet the same minimum bursting pressures. During manufacture of this tubing, final processing for both grades is the same: multiple cold-draw reductions; intermediate anneals; and a dead-soft anneal after final sizing of the tube. The result is tubing which is bendable and easy to flare, clean on the inside, and plugged or capped ends, to maintain cleanliness during shipment. We ship in cartons if required, for a nominal charge. The grades carried correspond to one of the following designations:

  1. Seamless - ASTM A-179 CDS or J524b
  2. Welded - SAE J525b
