7. Tighten the fitting lock nut (Step 4 in
A. Hold the fitting in the correct alignment with a wrench and use a torque
wrench and tighten the lock nut to the recommended torque value within
the specified range of torque values; refer to the
Table (page 5–12). This tightening procedure requires a drive-adapter
wrench (e.g., crowfoot wrench); refer to
When Using a Drive-Adapter Wrench (page
B. If a torque wrench is not available or if space at the port prevents the use
of a torque wrench, hold the fitting in the correct alignment with a wrench
and tighten the lock nut with a second wrench.
C. If the port material is steel (ferrous metal), tighten the fitting to the listed
Flats From Finger Tight (FFFT) value; refer to the
Tight (FFFT) Table (page
D. If the port material is non-ferrous, tighten the fitting to 60% of the listed
FFFT value; refer to the
5–12).
