INSTALLATION OF ABS AIR LINES
NOTE
Plastic air line tubing is connected to fittings with a brass ferrule
supplied with new fittings or replacement ferrule.
When installing air line tubing, length of tubing shall be trimmed so
there is a small amount of looseness when both ends are connected to
fittings and tubing is not so short it has to be pulled tight.
Prior to installation, ensure pipe joint compound is applied to male
pipe threads of fittings having National Pipe Threads (NPT) only.

Discard tubes (figure 44, items 4 and 5).
