Skiving Procedure
Skiving Weatherhead hose
Hand-tool method
Wire-Brush Method
!
Failure to completely remove the cover may result in serious personal injury or property damage
due to hose ends blowing off, hose leakage, and other failures.
Hose cut-off factor
Select the proper hose and ends and cut hose to length. The cut length of
the hose is determined by subtracting the cut-off factor for each end from
the overall length of the assembly. See individual catalog listings for hose
cut-off factors.
When using H425, H430, and H439 hoses with 430 ‘E’ series hose ends
and H470 hose with 470 ‘E’ series hose ends
The outer protective covering of wire-wrapped hose must be carefully
removed (skived) to the wire to allow proper installation of crimped hose
ends and to assure the best possible hose service.
There are two basic methods of skiving a hose: hand-tool and wire-brush.
Each method has specific advantages and should be used as shown below.
With either skiving method, it is advisable to skive a practice piece of hose
to determine that covering is properly removed and that the hose wire-
wrap reinforcements are not displaced, damaged or cut in the process. The
hose should be checked for correct skive length and 100% cover removal.
Position the end on a suitable mandrel and rotate the hose against a wire
brush to remove the protective covering. See above for correct skive length.
In some instances, and with care, the hose may be hand-held while being
skived. In either case, it is important that the covering be removed down to
the wire wrap, and that the wire wrap not be disturbed or damaged.
Skiving heads are shipped preset for proper skive length. Depending on hose
cover thickness, the skiving blade may require adjustment. The skiving blade
may need periodic adjustment. Directions are packed with the skive tool.
1.
Clamp hose in a vise or other suitable holding device. Be sure not to
clamp so tight as to damage hose.
2.
Lubricate hose I.D. and skiving tool mandrel with oil/soap solution.
3.
Carefully align mandrel with hose I.D.; apply steady pressure and start
mandrel into hose.
4.
When cutting head contacts hose end, slowly rotate skiving tool
clockwise. Cutting head will remove hose covering while threading itself
to a preset skive length when bottomed against hose end. Continue to
rotate skiving tool clockwise to remove excess rubber from wire wrap
while slowly pulling tool from hose. (See illustration below)
5.
Wire-brush hose end to remove any
remaining cover from wire wrap.
6.
Inspect skive for 100% cover removal.
Important: Clean hose I.D. by brushing,
blowing compressed air, or by flushing.
By doing so, contaminants are kept out of
operating systems.
