2. Place the tubeassembly against the fittingbody so that the flat
face of the flange tube (or braze sleeve) comes in full contact
with the O-ring. Thread the nut onto the fitting body by hand
and tighten it to the recommended torque: Seal-Lok(Table
T14) and Seal-Lok Lite(Table T15). If torque wrenches are
not available, an alternate method of assembly is the Flats
FromWrench Resistance (F.F.W.R.) method.Wrench tighten
the nut onto the fitting body until light wrench resistance is
reached. Tighten further to the appropriate F.F.W.R. value.
Note: A second wrench may be required to prevent the
fitting from moving during assembly.
Caution: The torque method of assembly is the preferred
method of assembly for Seal-Lok and Seal-Lok Lite fittings.
It reduces the risk of human error during assembly that
is more prevalent in the Flats From Wrench Resistance
(F.F.W.R.) method. To ensure the most accurate assembly
of the Seal-Lok fitting, it is strongly recommended that the
torque method be utilized.
