Crimp the hose/fitting assembly..
10.
Remove assembled end and check crimp diameter
with caliper or micrometer. Crimp diameter should
be measured at the center of the ferrule. Measure
the smooth portion of the ferrule and not the ridges.
Visually check for cracked, cocked or damaged fittings.
Verify crimp diameter with calipers.
11.
Even if not required, it is a good practice to examine
and audit the assembly before delivery or use. Records
should be maintained. The level of inspection should be
in compliance with the quality plan.
a) Inspection – Visual, dimensional and proof pressure
testing in accordance with SAE J517 or SAE J343.
b) Clean or flush of the assembly to remove plating
dust, rubber chips, etc.
c) Apply caps, if required, to protect fitting threads
and keep out contamination.
d) Apply labels or specific markings, if required.
e) Package the assembly properly.
Refer to the Final Inspection Checklist and Recommended
Inspection Equipment previously listed in “Hose Assembly
Instructions Using a 1-Piece Crimped Fitting.”
Hose Assembly Instructions
Field-Grip™ Fittings
Continental ContiTech Field-Grip™ reusable hose fittings
must be carefully matched to Continental ContiTech hose.
Use Field-Grip™ fittings only designed specifically for
Continental ContiTech hose. Use the correct socket with a
given hose. Specific fittings and their hose application can
be found in the fitting tables.
1.
Determine correct hose length from desired hose
assembly length and “C” dimension. The “C” dimension,
or cut-off factor, can be found in the fitting tables. More
information on using the “C” dimension can be found
in the previous subtopic, “Defining Hose and Assembly
Length.”
2.
Cut hose to the required length using a cut-off saw or
a circular abrasive cut-off wheel. The preferred choice
would be a steel wheel with a cooling agent. Care
should be taken in not overheating the hose, which can
cause deformation of the hose, creating difficulty when
inserting the hose fittings.
Steps in Hose Assembly
Cut-off saw. Use caution when operating power equipment.
Follow the proper safety measures per manufacturer suggestions.
