ASSEMBLY INSTRUCTIONS – TP7T, TP7TN, TP8T AND TP8TN TWIN HOSE
ASSEMBLY INSTRUCTIONS FOR:
SEPARATION OF THE ENDS OF TP7T, TP7TN, TP8T and TP8TN TWIN HOSE.
Note: RYCO TP7T, TP7TN, TP8T and TP8TN Hose must be separated at the ends to permit the attachment of the couplings. Procedure is as follows.
The latest RYCO Crimp Chart detailing Crimp Diameter and Mark Length is available from the RYCO website.
STEP ONE
90°
• Cut hose to length required using a sharp knife.
• Ensure hose is cut squarely.
• Clean hose bore.
STEP TWO
SEPARATION MARK LENGTH
• Arrange the end of the twin line hose so that it is lying straight and flat, resting on the bottom of both hoses, on a horizontal work surface.
• Mark the length to be separated on the cover of the hoses.
• The separation length required may vary depending on the crimper being
used.
• Separation length must allow each hose end to be inserted into the crimper
without kinking the other hose.
STEP THREE
• Hold the hoses flat on the work bench, and lightly score along the join between the two hoses with a blunt knife.
• Keep the knife vertical to avoid cover damage. It may be necessary to score along the join several times.
• Take care not to damage the covers of the hoses.
• Turn the hose over and repeat the above to score the other side of the join.
• The hoses will now be able to be separated by pulling apart.
• Inspect the covers to ensure there is no damage, if the cover is cut or the
reinforcement is exposed, the hoses must not be used.
STEP SEVEN
ADHESIVE TAPE
• After crimping the couplings, the hoses can be tied together at the separation area with tape or a cable tie to prevent the hoses becoming further separated accidentally.
STEP FOUR, FIVE, SIX
STEP 2 STEP 3
STEP 4
• Follow Step Two, Three and Four of page 491 Non-Skive Hose Assembly) for each end of the hose.
