RYCO T7000 Series Couplings With RYCO Skive Hose

Use only matched sizes of RYCO R4SP Series Hose.

Step One:

T7000 series step01
  • Cut hose to length required using a cut-off saw.
  • Ensure hose is cut squarely.
  • Clean hose bore.

Step Two:

T7000 series step02
  • Mark the Skive Length onto the hose. (Refer to “RYCO Crimp Chart”).
  • Cut rubber cover around and down to wire reinforcement then slit lengthwise.
  • Raise flap and pull off with pliers.
  • Measure coupling insertion depth and add a Mark Length Line on the outer cover as shown.

Step Three:

T7000 series step03
  • Push hose into the fitting (lightly lubricate the hose bore only if necessary as excess lubrication may reduce hose assembly impulse life) until the mark on the hose is even with the end of the ferrule.

Note: Push the hose all the way into the fitting.
Note: Do not use lubricant for hose to be used with volatile gases.

Step Four:

T7000 series step04
  • Place assembled end into jaws of crimp machine.
  • Operate machine to crimp ferrule to predetermined diameter. (Refer to “RYCO Crimp Chart”).

Step Five:

T7000 series step05
  • Open crimp machine and remove assembly.
  • Check crimp diameter with caliper or micrometer.
  • Crimp diameter should be measured halfway along the ferrule.
  • Measure between the ridges, and make sure that the caliper fingers do not touch the ridges.
  • Check that the ferrule still completely covers the skived part of the hose to ensure coupling has not moved during crimping.

Extra special care must be exercised in the preparation, assembly and crimping of these fittings due to the very high pressures and end loads encountered.
