1.2. Selection of the dies:
The selected crimping machine should be equipped with 3 set of dies:
Set of dies diameter 6,8 mm for GOMAX QUADRA DN2.
Set of dies diameter 9,0 mm for GOMAX QUADRA DN4.
Set of dies diameter 12,0 mm for GOMAX QUADRA DN6.
In order to obtain a correct final crimping diameter, which is fundamental to ensure the performance of
the assembled hose, the correct die set should be installed on the crimping machine which should be
set to achieve the final diameter of the crimped ferrule as listed in the table below (Table 1).
The die sets diameters indicated in table 1 are those specified for the crimping machine as used by
Transfer Oil for the production of GOMAX QUADRA hose assemblies. If the indicated die sets are not
available for the customers selected crimping machine then, before ordering the selected crimping
machine, please contact Transfer Oil Customer Service.
The use of inadequate dies sets, for example too small, will result in irregular shape and ridges on the
external surface of the ferrule and the assembly will not be able to sustain the pressure.
The use of a die set too big will cause the incapability of reaching the final crimping diameter of the
ferrule.
If among the dies available for your machine you are missing the suitable one, please don’t attempt to
crimp the fitting regardless, contact your assembling machine dealer to supply the missing die set.
