Ultra High-Pressure Hydraulic Products, Stainless Steel Range HP (over 20k to 60k PSI)

HP Collar and Gland Nuts, Stainless Steel

  • Acid resistant stainless steel 316L / EN1.4404 cold drawn.
  • Industry standard tubing sizes: 1/4", 3/8", 9/16"
  • Over 400MPa working pressure
  • Tested for cyclic pressure resistance
  • Full material traceability
  • Clearly marked individual components


Additional collar and gland nuts are also available. Suitable for CEJN’s hose tube fittings with left hand threads. They are easy to install, by mounting the gland nut on the tube and then threading the collar completely so the entire collar thread is engaged. Hand tighten the connection and then create the sealed with the specified torque.


Applications: Laboratories, high pressure hoses, connections, test rigs and calibration benches.
