E. O-RING FACE SEAL (ORFS)
HYDRAULIC FITTINGS
* Torque values and angles shown are based on lubricated
connection, as in re-assembly.
** Always default to the torque value for evaluation of adequate
torque.
*** O-ring face seal type end not defined for this tube size.
a. Check components to ensure that the sealing
surfaces and fitting threads are free of burrs,
nicks, and scratches, or any foreign material.
b. Apply lubricant (typically Petroleum Jelly) to
O-ring and threads. If O-ring is not already
installed, install O-ring. Align the tube or hose
assembly.
c. Ensure that flat face of the mating flange comes
in full contact with O-ring.
d. Thread tube or hose nut until hand-tight. The
nut should turn freely until it is bottomed out.
Torque fitting further to the specified number of
F.F.F.T (“Flats From Finger Tight”), or to a given
torque value in the table shown in the opposite
column.
NOTE
If available, always hold the hex on
the fitting body to prevent unwanted
rotation of fitting body and hose when
tightening the fitting nut.
e. When assembling unions or two hoses together,
three wrenches will be required.
