UTTING THE UBING CONT
Next, use a file to slightly bevel the
outside of the tube so that it will easily
slide into the fitting. Use steel wool or
a light grained sandpaper to buff the
surface of the tube which will be glued.
This will clean the tube and assure a
good seal. See figure at right.

Insert the tube into the fitting,
aligning the two parts as they
will be installed. Mark the tube
and the fitting so that you can
quickly realign the joint. See
figure at right.
Apply cement only to the
outside of the tube. Dab the
cement generously in
inch-wide band. Insert the
tube into the fitting with the
alignment marks a quarter turn
apart, and then quickly push
and turn the fitting to align the
marks and spread the cement.
Allow one minute for the joint to
dry. You may also use electrical
tape or duct tape to further seal
the joint. See figure at right.

EMENTING LEXIBLE
Make sure the ends of the flexible tubing are even—trim if
necessary. When you join flexible tubing to plastic tubing or to
an inlet mounting plate, apply cement to both the inside of the
flexible tubing and the outside of the plastic tubing or mounting
plate tubing ring. Twist the two pieces as you join them to
evenly spread the glue. Allow five minutes for the cement to set
in flexible tubing. You may also use electrical tape or duct tape
to further seal the joint.

ECURE IRE TO UBING
The low-voltage power wiring
is run along with the tubing. To
insure that the wire is secure
and will not hang-up in a wall,
use electrical tape to attach
the wire to the tubing. Tape
the wire approximately every
12-18 inches. See figure at
right.
