TORQUES FOR 0THER FITTINGS
Ermeto Tube Fittings
Put nut and sleeve over the tube with head or shoulder end
of sleeve next to nut. Push tube into counterbore of fitting
body as far as possible. Turn nut clockwise until sleeve holds
tube and prevents movement. Tighten the nut 1¼ turns more
to seat sleeve and give a locking action. When necessary to
assemble again, put sleeve over tube and tighten nut until a
sudden increase in torque is felt. Then tighten 1/6 to 1/3 turn
more to seat the sleeve.
Flex Fittings
Put nut and sleeve over tubing and push tube into
counterbore of fitting body as far as possible. Tighten the nut
until it is against the hex part of the fitting body.
Hi Duty (shear sleeve)
Tube Fittings
After tube has been put through the nut and makes
contact against the tube shoulder in the fitting body, turn the
nut with a wrench until a small decrease in torque is felt. This
is an indication that the sleeve has been broken off of the
nut. Hold the tube to prevent turning and tighten the nut 1
and 1/2 turns.
Hi Seal Fittings
Put nut and sleeve over the tubing with the short heavy
end of the sleeve facing the end of tubing. Put the tube end
against the counterbore in the body of the fitting and tighten
until nut is over the last thread on the body. The remainder
of space is used whenever the fitting is removed and installed
again
