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.
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.
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.
