Figure 10-49.--Marking tube.
Before you cut a tube, use a marking pen and a ruler
to draw a line parallel to the tube run across the section
to be cut (fig. 10-49). Cut the tubing. If a tube end is to
be replaced, make sure the line is placed in the same
location on the new tube as on the tube section that has
been removed. Draw a line across the fitting. Install the
tube run and locate the fitting. Fingertighten any end

bench if possible. Place the swaging tool on the first end
