Making a Joint

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 7.

Apply cement only to the outside of the tube. Dab the

cement generously in an 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 8.

Cementing Flexible Tubing

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.

Secure Wire to Tubing

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 9.
