Torque Procedure
Seal-Lok™ fittings
1 Replace the O-ring. The O-ring must be replaced
anytime the seal has been broken. The O-ring
cannot be re-used if the fitting or hose end has
been tightened beyond finger tight.
Note: The O-rings used in the Parker Seal Lok™
fittings and hose ends are custom-size O-rings.
They are not standard SAE size O-rings. They are
available in the O-ring field service kit (Genie part
number 49612).
2 Lubricate the O-ring before installation.
3 Be sure that the face seal O-ring is seated and
retained properly.
4 Position the tube and nut squarely on the face
seal end of the fitting and tighten the nut finger
tight.
5 Tighten the nut or fitting to the appropriate
torque per given size as shown in the table.
6 Operate all machine functions and inspect the
hoses and fittings and related components to
confirm that there are no leaks.
JIC 37° fittings
1 Align the tube flare (hex nut) against the nose of
the fitting body (body hex fitting) and tighten the
hex nut to the body hex fitting to hand-tight,
approximately 30 in-lbs / 3.4 Nm.
2 Make a reference mark on one of the flats of the
hex nut, and continue it on to the body hex
fitting with a permanent ink marker. Refer to
Figure 1.

3 Working clockwise on the body hex fitting, make
a second mark with a permanent ink marker to
indicate the proper tightening position. Refer to
Figure 2.
Note: Use the JIC 37° Fittings table on the previous
page to determine the correct number of flats for
the proper tightening position.
Note: The marks indicate that the correct tightening
positions have been determined. Use the second
mark on the body hex fitting to properly tighten the
joint after it has been loosened.
