Non--Adjustable Fitting (Fig. 4)
5.  If a torque wrench is not available, or if space at the
port prevents use of atorque wrench, an alternate meth-
od of assembly is the Flats From Finger Tight (F.F.F.T.)
method.
1.
Make sure all threads and sealing surfaces of fitting
and component port are free of burrs, nicks, scratches
or any foreign material.
A.  Install the fitting into the port and tighten it down
full length until finger tight.
2.
ommended that  the O--ring be  replaced any time  the
connection is opened.
As a preventative measure against leakage, it is rec-
B.  If port material is  steel, tighten the fitting  to the
listed F.F.F.T. If port material is aluminum, tighten fit-
ting to 60% of listed F.F.F.T.
3.

NOTE:  Use of an offset wrench (e.g. crowfoot wrench)
will affect torque wrench calibration due to the effective
length change of the torque wrench. Tightening torque
