Fluid Power Connector & Conductor

Connector & Conductor:

If you’re interested in testing for the Connector & Conductor certification, registration information can be found here.

The success or failure of any fluid power system depends on four factors: design, installation, start-up (commissioning), and maintenance. Hose and tube assemblies are a vital consideration in each of these factors as well as system and operating personnel safety. All Connector & Conductor certifications require a three (3)-hour written and a three (3)-hour job performance (hands-on) test.

A study manual has been prepared for candidates who wish to prepare for the Connector & Conductor Certification exam. It is recommended reading for engineers and those involved in selecting and applying hose and tube assemblies. The recommendations in this manual are not applicable to automotive hydraulic/pneumatic brake and power steering assemblies or aerospace equipment.


  • Understand basic components of hose construction
  • Identify hose types and pressure ratings
  • Identify port and fitting threads using measuring tools and charts
  • Identify the various two- and four-bolt flanges
  • Use appropriate charts to determine ratings for stainless and carbon steel tubing for application
  • Use the “Stamped” acronym to determine the correct hose and/or tube for correct assembly procedure
  • Understand metric and English values to ensure correct assembly of components
  • Square-cut hose to measured length
  • Know when and how to skive hose
  • Perform crimp machine inspection and calibration to ensure proper final hose assembly
  • Use caliper to measure crimp dimensions
  • Flare tubing to make assembly
  • Inspect Flareless tube assembly
  • Inspect twin ferrule tube assembly
  • Use silver brazing to assemble fittings to tube
  • Use hydraulic test stand for proof, burst, and impulse testing
  • Identify and use proper standards to ensure conformance and appropriate quality and safety
