• 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 FOUR
Mark Length
• Place assembled end into jaws of crimp machine.
• Operate machine to crimp ferrule to predetermined diameter.
(Refer to “RYCO Crimp Chart”).
NOTE
• 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.
• The latest RYCO Crimp Chart detailing Mark or Skive Length and Crimp Diameter is available from the RYCO website.
ASSEMBLY INSTRUCTIONS FOR:
RYCO T7000 SERIES COUPLINGS WITH RYCO SKIVE HOSE. USE ONLY MATCHED SIZES OF RYCO R4SP SERIES HOSE.
STEP ONE
• Cut hose to length required using a cut-off saw.
• Ensure hose is cut squarely.
• Clean hose bore.
STEP THREE
Mark Length
• 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 FIVE
• 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.
