From the calculation, and as shown in Figure 8, the plug should be inserted into the
fitting until the distance from the top of the
Compression Hex Nut(21)
to the end of
the fitting is 14.72”.

CAUTION:
Gripping failure may occur if the Gripping Wedges are not fully inserted into
the pipe or fitting. If any of the
Wedge Gripper’s(16)
surface is visible beyond the end
of the pipe or fitting end, represented in Figure 10, the GripSafe plug may not hold any
backpressure. Advancement of the plug into the vessel being tested is necessary so
none of the
Wedge Gripper’s(16)
surface is visible beyond the end of the pipe or fitting
end shown in Figure 9. Care should be taken to not cover the weld area with the
Seal(14)
as it could render a false outcome of a hydrotest.
