Making Hydraulic Hoses

Printer Friendly Version 		Safety and Health are Values!


A crucial part of hydraulic hose safety depends on the care taken when fabricating the hose assemblies. Failure of a pressurized hose assembly creates a potential for personal injury to equipment operators or anyone working near the equipment, fire, and equipment damage.

Fabricating techniques to minimize hydraulic hose failures include:
  • Do not inter-mix manufacturers. Use the same manufacturer's products for all parts of the assembly (end fittings, hose, etc.) and make sure you use the corresponding manufacturer's hose machine for crimping.


    • Making Hydraulic Hoses
  • Know the crimp specifications to include:

      1) Type of hose
      2) Type of end(s) approved for the hose
      3) Correct die for crimping
      4) Correct crimp setting
      5) Allowable finished crimp outer diameter (O.D.)
