(a) When using the flanging tool (fig 21). hold the tubing in the hand;
do not rest the opposite end on a solid object as this may damage the tubing. Keep
the tool centered and straight, and tap it into the tubing until the flare fills
the recess in the flange nut.
(b) When using the two-piece flaring tool (fig 21), place the tubing in
the proper size hole with the tubing end level with the surface of the tool. Turn
down the cone on the yoke until the flare on the tubing fills the beveled portion
of the hole.
Using the flaring tool.
(4) Join the flared end of the tubing to the ground joint on the fitting
and inspect for proper fit.
(5) Slide the nut back up to the flared end of the tubing (fig 22) and
screw it on the male thread of the fitting until it is tight;
Making up a flared fitting.
(6) Finish making the connection by tightening the nut with wrenches (open
or monkey), one on the nut and the other on the fitting. Never use one wrench
alone; if the fitting is not held in place with a second wrench, it will turn and
may spoil the connection at the other end.
