Assembly Instructions
Use of a PST (Manual Pre Setting Tool) is
recommended
GYROLOK
®
Marking Tool (GMT)
is strongly recommended
.
Fully insert a correctly cut, deburred
tube into the PST or fitting body
until the tube rests on the sizing
angle.
Holding the tube in the PST or
Body, extract the nut and
ferrules to visually ensure both
ferrules are correctly oriented.
Once correct ferrule orientation
is confirmed, thread & rotate the nut
onto the PST or Body until hand-
tight. The GMT witness line should
NOT
be visible.
Establish a reference point for
wrench tightening by marking both
the fitting body and nut.
While supporting the PST or fitting
body, tighten the nut with a wrench
1¼ turns. The pre-set or make-up is
now complete. Confirm that the GMT
witness line is now visible.

Ensure the HPST Tooling Set is installed with the proper indicator nut.
Insert the correctly cut and
deburred tube into the GMT as far
as possible.
Mark the tubing as shown with an
Ultra-Fine Point, Chloride-Free
pen (recommended Sharpie Model
37001). Take care to position the
marker perpendicular to the GMT, or
insufficient ferrule set could occur.
Fully insert a correctly cut,
deburred tube into the HPST
head. Visually ensure both ferrules
are correctly oriented. Thread &
rotate the nut until hand-tight.
Set the indicator arm in the
operating position by rotating the
Indicator Nut counter-clockwise
until it stops.
Pump the handle until the
indicator arm releases.
CAUTION:
Stop pumping
immediately after the arm
releases, as over-pumping may
cause the tube to swell and stick.
Pre-setting is now complete.
Insert the end with pre-set ferrules
and nut into the fitting. Thread
and rotate the nut until hand-tight.
While supporting the fitting body,
tighten the nut with a wrench
