Using a power hose cutoff saw,
cut hose squarely.
Cut
Hose –
Visually inspect both
ends of hose for square cut.
Remove any burrs, loose fibers
or wires.

corresponds to the selected
hose. Visually inspect fitting(s)
for a through-hole, threads and
damage.

Inspection
Insertion Depth –
Mark hose
end with proper insertion depth
line. See Hose Fitting Insertion
Values, pg
. G-42
for insertion
depths of fitting series that do
not incorporate an insertion
depth. For jacketed PTFE
hoses, use a sharp knife and
light pressure to cut back the
cover at least the length of the
insertion depth of the fitting.
Warning
Do not use lubricating oil when
installing fittings on hose used in
oxygen service. When installing
fittings on hose used in oxygen
service, lubricate with a non-oil
based soap solution. Failure to
do so may result in an explosion
and personal injury when hose
is used.

Note
PTFE Hose should be taped
prior to cutting. Hose should
be cut at center point of taped
section.
CAUTION:
There are several different sections for Hose Assembly
and Crimping. Be sure you are in the section that corresponds to
