in this video you will see a
side-by-side installation of swagelok fk
series tube fittings and traditional
cone and thread fittings an fk series
fitting is installed on the left cone
and thread installation occurs on the
right shown at two times the speed
right away you will see that fk series
fittings can be installed with just a
common wrench
vise and inspection engaging tools
on the right the installer prepares
special tooling required to make cone
and thread fitting as the cone and
thread installer prepares the tube the
fk series fitting installer simply
threads the fk series fitting cartridge
into the body and removes the plastic
arbor from the end of the nut while the
cone and thread installer applies the
cutting lubricant the fk series
installer inserts the tubing into the
fitting body and marks the depth to
ensure assembled alignment
no special prep or cutting lubricant is
required
on the left the fk series installer
applies one full turn to complete the
connection meanwhile on the right the
installer continues to form the cone on
the tube
the fk series installer checks the
assembly with the swagelok medium
pressure gap inspection gauge the gauge
does not enter the gap indicating he is
finished the fitting is ready to go
on the right the conan thread installer
checks the end of his prepared tube a
deburring operation is required to
remove metal shavings
[Music]
the installer is now ready to thread the
tubing using cutting fluid the threading
tool is turned clockwise until it is
parallel to the ground and the groove on
the threading die is facing up
to thread the tube the installer applies
pressure to the tool while rotating it
counterclockwise
[Music]
as the installer threads the tube
metallic debris falls from the
installation when using fk series
fittings installers do not need to worry
about shavings or lubricant as a
contamination risk
proper coning and threading is a skilled
process and requires a knowledgeable
installer an experience can lead to
improperly threaded connections that can
leak after inspecting the tube for an
acceptable surface finish he slides the
fitting gland onto the tubing next the
collar is threaded counterclockwise onto
the tubing
he continues threading until one to two
full threads are exposed at the cone end
once the collar is threaded onto the
tubing the installer slides the gland
nut over the tubing and inserts the
tubing with the collar into the fitting
body the fk series integrates most of
these individual components within the
fitting cartridge finally the installer
tightens the fitting to its required
torque value he is finished as you can
see the fk installation was
approximately five times faster and
would have virtually eliminated any
rework the fk series is comparable to a
typical swagelok tube fitting by
drastically reducing installation time
and delivering consistent leak tight
performance fk series fittings can help
deliver significant cost savings to
