CRIMPING
There are several different crimping procedures described,
depending on the coupling which is to be applied . No matter
what style of crimp is used the same safety rules apply .
■
Assemblies must be fabricated only from NEW
(Unused) Gates hose and couplings .
■
Always consult the most current crimp data available
to check the crimp specifications and machine
settings .
■
Load the recommended die set into the crimper .
Properly lubricate the crimper dies, but do not
lubricate the bore of the die .
■
Always wear safety glasses
■
Keep hands away from moving parts of the crimper .
■
For any questions consult the crimper operation
manual or Gates technical support .
■
All settings are approximate! Variation due to
tolerances and wear may exist, always measure the
finished crimp diameter .
FULL LENGTH CRIMP ONE-PIECE COUPLINGS (G, P,
GSM, MGS)
When installing 1 piece couplings it is recommended that the
hose is marked with the insertion depth from each cut end . This
way there is a mark to verify the coupling has been fully inserted
into the hose .
These types of couplings require a full length crimp, shown in
Figure 7 . In order to form the full length crimp the edge of the
coupling should be inserted into the die approximately 1/8”
past the die edge . This will ensure that the entire ferrule is
crimped, without a bubble near one end .

FULL LENGTH CRIMP TWO-PIECE COUPLINGS (GS,
GSP, PC, B & S STAINLESS STEEL)
When installing 2 piece couplings (with separate stem and
ferrule) place the ferrule onto the cut hose then insert the stem
into the hose . If stem insertion is very difficult the serrations
may be lubricated with light oil, and if necessary the coupling
restrained in the jaws of a vice . Be sure that the hose is fully
inserted onto the stem by moving the ferrule and visually
inspecting . When crimped the ferrule must be latched into the
stem shoulder, see figure 9 .
These types of couplings require a full length crimp, see Figure
8 . In order to form the full length crimp the edge of the coupling
should be inserted into the die approximately 1/8” past the die
edge . This will ensure that the entire ferrule is crimped, without
a bubble near one end . Before making the crimp be sure ferrule
is engaged in the stem latching collar .
