Then, tighten the nut an additional one turn
past the ring grip point.
Unscrew nut and remove the tubing from
the mating fitting, or presetting tool. Inspect
the preset as described in Figure 6-1.
When installing a preset tubing assembly,
lubricate the threads and seat of the fitting
and the shoulder of the sleeve with a small
amount of good grade lubricant such as
clean compressor oil.
At installation of tubing assemblies, do not overtighten
Insert tubing assembly into fitting and
tighten nut until a sharp rise in torque is felt.
Starting at position of sharp torque rise,
tighten the nut 1/4 additional turn to
complete the assembly.
At the point where the torque starts to rise, the sleeve
and tubing are just touching the seat. An additional 1/4
turn produces a seal with the fitting and restores the bow
to the sleeve.
(3) Replace damaged or defective fittings.
