Hose Assembly & Crimping
Verify the type and size hose
printed on layline match work
order.
NOTE:
When calculating hose length,
take into consideration the
change in hose length (expan-
sion/contraction) that may occur
during pressurization.
Using a flexible or rigid measur-
ing tape, measure the length of
hose required as follows:
a. Verify required length of hose
assembly with fittings.
b. Subtract “Cutoff Allowance”
of each fitting from hose as-
sembly length. (Refer toHose
Fittings Tables in Catalog
4660 for proper cutoff allow-
ances)
EXAMPLE:
Hose assembly length with fittings
= 12"
Fitting Cutoff Allowance
(125HBL-6-6) 3/4"
Fitting Cutoff Allowance
(125HBL-6-6) 3/4"
Total Cutoff Allowance 1-7/16"
12"- 1-7/16" = 10-9/16"
Length of hose required = 10-9/16"
Secure hose in some type of
fixture to ensure straightness.
Measure and mark hose.
CAUTION:
Do not use abrasive wheels to
cut hose. Abrasive wheels will
damage core tube.
Tape hose securely so mark is
in center of tape and mark tape.
919U hoses can not be taped.
MEASURE & CUT
HOSE TO LENGTH 1 MEASURE & CUT
HOSE TO LENGTH 2 MEASURE & CUT
HOSE TO LENGTH 3
Using a Parker Model 316 cutoff
tool, Parflex PHC hand cutter
or other sharp cutter, cut hose
squarely to correct length.
Using a Parker Model 332-T-
115V Hose Cutoff Machine or
fine-toothed hacksaw, cut hose
squarely to length.
A power hose cutoff saw should
always be used on PTFE and
wire reinforced thermoplastic
and hybrid hoses.
