Skiving Procedure

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.

Skiving Weatherhead hose

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.

Wire-Brush Method

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.

Hand-tool method

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.

Clamp hose in a vise or other suitable holding device. Be sure not to

clamp so tight as to damage hose.

Lubricate hose I.D. and skiving tool mandrel with oil/soap solution.

Carefully align mandrel with hose I.D.; apply steady pressure and start

mandrel into hose.

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

Skiving Method

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.

# When used with 430 'E' series hose ends

rotate skiving tool clockwise to remove excess rubber from wire wrap

while slowly pulling tool from hose. (See illustration below)

Wire-brush hose end to remove any

remaining cover from wire wrap.

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.
