When should I use the aluminum supply tubing?

Aluminum tubing is known for its durability and strength. In the event of a torn outer jacket, air will not escape, ensuring efficient airflow. It is suitable for long runs that involve navigating walls and attics with sharp corners. Aluminum tubing is available in a convenient 25 ft. length and is also cost-effective compared to sound attenuator. If desired, you can combine aluminum tubing with sound attenuator, but it is important to note that the last 3 ft. or more must be sound attenuator. To join or extend lengths, installation kits include couplings.
