Care must be taken when crimping clamp collars onto a
hydraulic hose. If crimp is too tight, hose will be crushed,
dramatically reducing its service life. If crimp is too loose, collar
could slide along hose’s length causing abrasion and eventual
hose cover failure.
Remember: Clamp collars must be crimped before the hose
couplings.
Use the following instructions to determine crimp diameter,
which can then be used to find crimping setting in Table 2. The
required clamp collar for a specific hydraulic hose is provided
in Table 1.
1. Measure hose’s outside diameter at the location where
clamp collar will be crimped. This can be accomplished
by using a pie tape or by using the average hose outside
diameter measured with a dial caliper.
2. Obtain crimp diameter by adding hose outside diameter to
twice the clamp collar wall thickness
(see formula below).
CRIMP DIAMETER = (HOSE O.D.) + [2 X .065 (CLAMP
COLLAR WALL THICKNESS)]
When crimping clamp collar, the crimp die should be located in
the center of the collar, which will result in a 1/8” flare on each
side of the collar.
